Gas Guzzlers Extreme PC Game Full version


Review:
Gas Guzzlers Extreme, for no sensible reason, reminds me of a racing game I thoroughly enjoyed and yet have never heard a single other human mention: Beetle Crazy Cup. It came out in 2000, from Infrogrames as was, by the entirely unknown Xpiral. It was a VW-licensed game that I gave it 85% in PC Gamer back then, and I don’t think a single person bought it. I bring this up, because I’m struggling to find too many interesting things to say about Gas Guzzlers Extreme.


That’s not to say it’s a disaster. It’s incredibly clumsy, but the issue here is that it’s just a touch bland. It’s, well, a driving game with shooting in it. It’s Mario Kart with proper cars, and utterly without the intuitive delivery. Have I enjoyed my brief go? A bit. I haven’t hated it. I’ve driven around a few tracks, done well, done badly, shot at other cars and been shot at. And, it all feels awfully familiar.


There’s a definite desire to go big, but unfortunately little actual delivery. So while it seems to think it’s delivering big explosions and violence, it’s all rather tempered and ordinary, the real pleasure of an anarchic driving game buried in a confusion of obscurity. Everything is just so incredibly vague, from whether you’ve clipped a floating bonus item to pick it up to what bonus you currently have to whether you’ve deployed it. The Arcade mode offers generous cornering and liberal use of handbrakes, and that’s my sort of racing, but all the other cars seem to be having a lot more fun than me. I can see the mines they’ve dropped – I’ve no idea if I’ve ever dropped mine.

There’s a garage, cars to be bought and augmented with won money, exactly as you’d expect. You begin with a Reliant Robin, then move onto a Beetle – you get the idea there. But you can attach weapons, boost engines, etc, and then take part in the heavily rubber-banded racing that’s a mad cluster of short-cuts and frustration as other drivers crash into you. That’s an issue solved by jumping online, of course, where such actions feel far more fair when done at you by another human. Although that’s a bit tricky here – at the time of writing there were a total of seven people playing, and the game wouldn’t let me join the one populated race. Which is actually a shame, as the deathmatch mode against the AI is quite fun. It has potential online.

However, I really wasn’t too impressed with a new game in late 2013 turning Win 7 down to Basic mode, nor refusing to launch until I’d set my desktop resolution to 1024×768.
But what has this to do with Beetle Crazy Cup, you ask. Good point. Read more

Creating a Pentomino game using AS3 Part 38

Today we will add the ability to browse through the solutions.

Firstly declare a new variable - currentSol. Set its value to 0 by default. This variable represents the id of the solution that is currently displayed.

private var currentSol:int = 0;

Open the project in Flash and go to fifth frame (the solutions screen). Add two buttons shaped like arrows with ids btn_prev and btn_next. Add a dynamic text field with id tSol, it will display which solutions is currently is shown.

Go to level_solver.as again and in the solve() function add CLICK event listeners for btn_prev and btn_next. Set handlers to goPrev and goNext functions:

btn_prev.addEventListener(MouseEvent.CLICK, goPrev);
btn_next.addEventListener(MouseEvent.CLICK, goNext);

The functions decrease/increase currentSol values and call updateCurrentInfo() function.

private function goPrev(evt:MouseEvent):void {
currentSol--;
updateCurrentInfo();
}

private function goNext(evt:MouseEvent):void {
currentSol++;
updateCurrentInfo();
}

The same function is called in nextCycle():

private function nextCycle():void {
cycleNum++;
updateCurrentInfo();
if (cycleNum == givenShapes.length) {
removeEventListener(Event.ENTER_FRAME, onFrame);
// display info
tInfo.text = Finished solving " + levelName + "
Attempts:  + attempts + "
Solutions: " + solutions.length;
}
}

The function updates what is displayed in the tSol text field, disables/enables arrow buttons when needed, draws the preview image:

private function updateCurrentInfo():void {
var sol:int = (solutions.length > 0)?(currentSol + 1):(0);
tSol.text = sol + "/" + solutions.length;
if (sol <= 1) {
btn_prev.alpha = 0.5;
btn_prev.mouseEnabled = false;
}else {
btn_prev.alpha = 1;
btn_prev.mouseEnabled = true;
}
if (sol == solutions.length) {
btn_next.alpha = 0.5;
btn_next.mouseEnabled = false;
}else {
btn_next.alpha = 1;
btn_next.mouseEnabled = true;
}
if (solutions.length > 0) drawPreview(levelPreview, solutions[currentSol]);
}

Update the drawPreview() function so that cells are colored depending on the shape type:

private function drawPreview(levelPreview:MovieClip, mapGrid:Array):void {
var columns:int = mapGrid[0].length;
var rows:int = mapGrid.length;
var frameWidth:int = levelPreview.width;
var frameHeight:int = levelPreview.height;
var padding:int = 5;
var fitWidth:int = levelPreview.width - (padding * 2);
var fitHeight:int = levelPreview.height - (padding * 2);
var gridStartX:int;
var gridStartY:int;

// calculate width of a cell:
var gridCellWidth:int = Math.round(fitWidth / columns);

var width:int = columns * gridCellWidth;
var height:int = rows * gridCellWidth;

// calculate side margin
gridStartX = (frameWidth - width) / 2;

if (height < fitHeight) {
gridStartY = (fitHeight - height) / 2;
}
if (height >= fitHeight) {
gridCellWidth = Math.round(fitHeight / rows);
height = rows * gridCellWidth;
width = columns * gridCellWidth;
gridStartY = (frameHeight - height) / 2;
gridStartX = (frameWidth - width) / 2;
}

// draw map
levelPreview.shape.x = gridStartX;
levelPreview.shape.y = gridStartY;
levelPreview.shape.graphics.clear();
var i:int;
var u:int;

for (i = 0; i < rows; i++) {
for (u = 0; u < columns; u++) {
if (mapGrid[i][u] == 1) drawCell(u, i, 0xffffff, 1, 0x999999, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 2) drawCell(u, i, 0xff66cc, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 3) drawCell(u, i, 0x00FF66, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 4) drawCell(u, i, 0x99ff00, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 5) drawCell(u, i, 0x00ccff, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 6) drawCell(u, i, 0xffcc66, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 7) drawCell(u, i, 0x66cc33, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 8) drawCell(u, i, 0x9900ff, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 9) drawCell(u, i, 0xff5858, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 10) drawCell(u, i, 0xff6600, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 11) drawCell(u, i, 0x00ffff, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 12) drawCell(u, i, 0xff6b20, 1, 0x000000, gridCellWidth, levelPreview.shape);
if (mapGrid[i][u] == 13) drawCell(u, i, 0xffff66, 1, 0x000000, gridCellWidth, levelPreview.shape);
}
}
}

Now we can browse through the solutions!

Creating a Pentomino game using AS3 Part 9

Today well improve our shape placing code, as well as make all shapes available for placing.

First of all, well create a function that draws a preview of where the shape will be placed exactly. We need to declare a new Sprite object for this - canPutShape:

private var canPutShape:Sprite = new Sprite();

And add it to the stage after creating the grid:

// can put shape
addChild(canPutShape);
canPutShape.x = gridStartX;
canPutShape.y = gridStartY;

The function uses some of the already used code in the script, slightly modified. We simply loop through the currentValues and draw each cell:

private function drawCanPut():void {
canPutShape.graphics.clear();
var mousePos:Point = new Point(Math.floor((mouseX - gridStartX) / gridCellWidth), Math.floor((mouseY - gridStartY) / gridCellWidth));
for (var i:int = 0; i < currentValues.length; i++) {
var cellX:int = (currentValues[i][0] + mousePos.x) * gridCellWidth;
var cellY:int = (currentValues[i][1] + mousePos.y) * gridCellWidth;
canPutShape.graphics.beginFill(0x00ff00, 0.1);
canPutShape.graphics.drawRect(cellX, cellY, gridCellWidth, gridCellWidth);
}
}

Now go to mouseMove() and instead of the selectedShape if statement call a function called checkPut():

private function mouseMove(evt:MouseEvent):void {
cursor.x = mouseX;
cursor.y = mouseY;
checkPut();
}

The functions code is the same, but has a few modifications. We check if canPutHere is tru or false and set the cursors alpha to represent whether its possible or not to place the selected shape here. We also clear canPutShapes graphics if canPutHere is false.

private function checkPut():void {
if (selectedShape > 0) {
var mousePos:Point = new Point(Math.floor((mouseX - gridStartX) / gridCellWidth), Math.floor((mouseY - gridStartY) / gridCellWidth));
canPutHere = true;
updateCurrentValues();
for (var i:int = 0; i < currentValues.length; i++) {
var cellX:int = currentValues[i][0] + mousePos.x;
var cellY:int = currentValues[i][1] + mousePos.y;
if (cellX < 0 || cellY < 0 || cellX >= mapGrid[0].length || cellY >= mapGrid.length || mapGrid[cellY][cellX]!=1) {
canPutHere = false;
}
}
if (canPutHere) {
cursor.alpha = 0.8;
}
if (!canPutHere) {
canPutShape.graphics.clear();
cursor.alpha = 0.4;
}
}
}

Where is drawCanPut() called if not in checkPut(), you ask? Thats in updateCurrentValues(), but only after weve added a few modifications to the code inside updateCurrentValues(). These bugs were found after I implemented the "shadow" feature thats drawn by drawCanPut(), and you can see the updated code below:

private function updateCurrentValues():void {
currentValues = clone(shapeValues[selectedShape-1]);
for (var i:int = 0; i < 5; i++) {
if (cursor.rotation == 90) {
currentValues[i].reverse();
currentValues[i][0] *= -1;
}
if (cursor.rotation == 180 || cursor.rotation == -180) {
currentValues[i][0] *= -1;
currentValues[i][1] *= -1;
}
if (cursor.rotation == -90) {
currentValues[i].reverse();
currentValues[i][1] *= -1;
}
if (cursor.scaleX < 0 && (cursor.rotation != -90 || cursor.rotation != 90)) {
currentValues[i][0] *= -1;
}
if (cursor.scaleX < 0 && (cursor.rotation == -90 || cursor.rotation == 90)) {
currentValues[i][0] *= -1;
currentValues[i][1] *= -1;
}
}
drawCanPut();
}

Call checkPut() instead of updateCurrentValues() in mouseWheel() and keyDown():

private function mouseWheel(evt:MouseEvent):void {
if (evt.delta > 0) cursor.rotation += 90;
if (evt.delta < 0) cursor.rotation -= 90;
if (selectedShape > 0) checkPut();
}

private function keyDown(evt:KeyboardEvent):void {
if (evt.keyCode == 68) cursor.rotation += 90;
if (evt.keyCode == 65) cursor.rotation -= 90;
if (evt.keyCode == 32) cursor.scaleX *= -1;
if (selectedShape > 0) checkPut();
}

Now we can update the shapeValues() array. Simply add each shape cells relative coordinates:

shapeValues = [
[[0, 0], [0, 1], [0, 2], [0, -1], [0, -2]],
[[0, 0], [0, -1], [0, 1], [1, 0], [1, -1]],
[[0, 0], [0, 1], [0, 2], [0, -1], [ -1, -1]],
[[0, 0], [0, 1], [0, -1], [ -1, 0], [1, -1]],
[[0, 0], [ -1, 0], [ -2, 0], [0, -1], [1, -1]],
[[0, 0], [0, 1], [0, -1], [1, -1], [ -1, -1]],
[[0, 0], [1, 0], [ -1, 0], [1, -1], [ -1, -1]],
[[0, 0], [ -1, 0], [ -2, 0], [0, -1], [0, -2]],
[[0, 0], [0, 1], [ -1, 1], [1, 0], [1, -1]],
[[0, 0], [0, 1], [0, -1], [1, 0], [ -1, 0]],
[[0, 0], [ -1, 0], [ -2, 0], [1, 0], [0, -1]],
[[0, 0], [0, 1], [1, 1], [0, -1], [-1, -1]]
];

Creating a Pentomino game using AS3 Part 8

In this part we will add the ability to place rotated shape on the grid.

In the previous tutorials we used internal (temporary) variable inside several functions named currentValues. Lets make this a private variable available in all functions:

private var currentValues:Array = [];

So in mouseMove(), instead of setting value to this variable we call updateCurrentValues():

private function mouseMove(evt:MouseEvent):void {
cursor.x = mouseX;
cursor.y = mouseY;
if (selectedShape > 0) {
var mousePos:Point = new Point(Math.floor((mouseX - gridStartX) / gridCellWidth), Math.floor((mouseY - gridStartY) / gridCellWidth));
canPutHere = true;
updateCurrentValues();
for (var i:int = 0; i < currentValues.length; i++) {
var cellX:int = currentValues[i][0] + mousePos.x;
var cellY:int = currentValues[i][1] + mousePos.y;
if (cellX < 0 || cellY < 0 || cellX >= mapGrid[0].length || cellY >= mapGrid.length || mapGrid[cellY][cellX]!=1) {
canPutHere = false;
}
}
}
}

Call the same function in mouseWheel and keyDown if there is a shape thats selected:

private function mouseWheel(evt:MouseEvent):void {
if (evt.delta > 0) cursor.rotation += 90;
if (evt.delta < 0) cursor.rotation -= 90;
if (selectedShape > 0) updateCurrentValues();
}

private function keyDown(evt:KeyboardEvent):void {
if (evt.keyCode == 68) cursor.rotation += 90;
if (evt.keyCode == 65) cursor.rotation -= 90;
if (evt.keyCode == 32) cursor.scaleX *= -1;
if (selectedShape > 0) updateCurrentValues();
}

Go to mouseUp() and add a line that sets the new shapes rotation to cursor.rotation:

private function mouseUp(evt:MouseEvent):void {
stopDragShape();
if (selectedShape > 0) {
if (!canPutHere) {
availableShapes[selectedShape-1]++;
shapeButtons[selectedShape-1].count.text = availableShapes[selectedShape-1];
selectedShape = 0;
}
if (canPutHere) {
var mousePos:Point = new Point(Math.floor((mouseX - gridStartX) / gridCellWidth), Math.floor((mouseY - gridStartY) / gridCellWidth));
var newShape:MovieClip = new game_shape();
addChild(newShape);
newShape.x = gridStartX + (mousePos.x+1) * gridCellWidth - gridCellWidth / 2;
newShape.y = gridStartY + (mousePos.y + 1) * gridCellWidth - gridCellWidth / 2;
newShape.rotation = cursor.rotation;
newShape.scaleX = cursor.scaleX;
newShape.scaleY = cursor.scaleY;
newShape.gotoAndStop(selectedShape);
for (var i:int = 0; i < currentValues.length; i++) {
var cellX:int = currentValues[i][0] + mousePos.x;
var cellY:int = currentValues[i][1] + mousePos.y;
mapGrid[cellY][cellX] = 2;
}
cursor.parent.setChildIndex(cursor, cursor.parent.numChildren - 1);
selectedShape = 0;
}
}
}

Now create a new function called clone(). This will be used to clone an array with arrays inside of it properly:

private function clone(source:Object):*{
var myBA:ByteArray = new ByteArray();
myBA.writeObject(source);
myBA.position = 0;
return(myBA.readObject());
}

Add updateCurrentValues() function. Here in the first line we clone the respective element in shapeValues and apply that value to currentValues.

Then we loop through all the 5 elemenst of it, and go through a few if statements to modify the values. If cursors rotation is 0, we dont need to change anything, since the values in currentValues apply here. If the shape has rotation 90, we need to reverse the values of each element (x becomes y and y becomes x). If the rotation is 180 or -180, we inverse the values by multiplying them by -1. If the rotation is -90, inverse and reverse the values. If scaleX of cursor is less than 0, inverse the X values:

private function updateCurrentValues():void {
currentValues = clone(shapeValues[selectedShape-1]);
for (var i:int = 0; i < 5; i++) {
if (cursor.rotation == 90) currentValues[i].reverse();
if (cursor.rotation == 180 || cursor.rotation == -180) {
currentValues[i][0] *= -1;
currentValues[i][1] *= -1;
}
if (cursor.rotation == -90) {
currentValues[i].reverse();
currentValues[i][0] *= -1;
currentValues[i][1] *= -1;
}
if (cursor.scaleX < 0) {
currentValues[i][0] *= -1;
}
}
}

Now we can drag, rotate, and drop the first shape properly.
