[F8][WIP] Invasion 5

i hate to be a douchebag, but wat's supposed to be fun about this?

the performance is incredible... im really amazed at how you do it, but the game just isnt fun. its really repetitive and dull... and the only unit that becomes any use later in the game is the canoneers

(and it'd go even slower if you worked it out mathematically - ie, writing your own hitTest() - a hundred times slower ).

Vengeance, i made some tests with math square to square,my way, with the summ of the radius pre calculated and the results were that it was faster then circle to circle without sqrt.I posted the results in a thread called as3 hittest cos at first i was thinking it would work only for as3, but its faster for as2 too.
But as noone cares about it this is the last time i will talk about it.

Playing flash games is research... yes... research.

Hmmm. Actually in it's current form the game doesn't require any micro management. It was a case of buying a load of knight, release all of them at the start, then minimising the window. Do a bit of work, have a look a bit later. The castle would be destroyed and I'd do another level.

Even if that's the case, I'm not using circle to circle collision, so it'd still be slower. It doesn't change the fact that it'd still have to do hundreds and hundreds of extra collision checks.

@johnnyblazedx:
Currently it's no fun at all (even I'll admit it ) because it's devoid of strategy and challenge (due to a lack of balancing, and no tactical advantage to mixing unit types). Once I've added a few of the ideas presented in this thread (and started balancing everything), it'll start to get a lot more fun. But challenging or not, I still think there's something awe-inspiring about seeing so many people breaking upon a castle, like rocks upon water (LotR quote, I know ).

@happinessSam:
If you want micromanagement, I could add it, but the game was never meant to be like that. It was only ever intended to be a role-reversal of Defend Your Castle. Besides, if you micro-managed, you'd be able to move your archers away from the castle's line of fire, or tell your guys to stop walking when the arrows appear. It'd negate the challenge of the game.

However, I am considering making it so that you could cast spells with your mouse, such as drawing a line above your troops, which would act as a barrier to shelter them from incoming arrows.

ever thought about adding armor upgrades so they don't die in one hit? maybe for a much more expensive cost?

[VENGEANCE MX]

Did think of it, yes, but even 1 extra HP will double the survival rate of most units. In one distro of the game, infantry had 2 HP and never lost a match.

Hi,

Just wondering if anybody has any pointers for getting the destructible terrain to scroll as in micro warriors (http://www.birchlabs.co.uk/Micro%20Warriors.swf). As soon as I move the terrain the holes no longer appear in the right places.

Posting the code you're using would be a good start.

Hi. To make this work you need three movieclips: dot, ground and hole. Pretty straightforward, but as soon as I use my scrolling function things get screwed up. The scrolling function is below as well. Thanks so much for the help!!

//the code

import flash.display.BitmapData;
import flash.geom.*

gravity=3

var myCT:ColorTransform = new ColorTransform (1, 1, 1, 1, 0, 0, 0, 0);
var my_mc:MovieClip = this.createEmptyMovieClip ("mc", 1);
var myBmp:BitmapData = new BitmapData (Stage.width, Stage.height, true, 0x00000000);

//levelBitmap.draw(ground, m);
myBmp.draw (ground, myMatrix);

my_mc.attachBitmap (myBmp, 0, "never", false);
this.attachMovie ("hole", "hole_mc", 2);
this.attachMovie ("ground", "ground", 3);
this.attachMovie ("dot", "dot", 4);
dot._x=200
hole_mc._x = -100;
//make first hole
var myMatrix:Matrix = new Matrix ();
myMatrix.translate(ground._x, ground._y)
myBmp.draw(ground, myMatrix);
ground.swapDepths(_root.getNextHighestDepth());
removeMovieClip(ground);

onMouseDown = function () {
var myMatrix:Matrix = new Matrix ();
myMatrix.translate (this._xmouse - hole_mc._width / 2, this._ymouse - hole_mc._height / 2);
myBmp.draw (hole_mc, myMatrix, myCT, "erase");
};
onEnterFrame = function () {
//get the pixels
if (myBmp.getPixel (dot._x, dot._y + 1) == 0) {
dot._y+=gravity;
}
};


//and the scrolling function

function scrollControll(ob){

ob._x += (((Stage.width/2)-scrollAdjustHorizontal/3.5-center._x)/10)*friction;

ob._y += (((Stage.height/2)-scrollAdjustVertical/3.5-center._y)/10)*friction;

}

scrollAdjustHorizontal = DistanceBetweenHorizontal(center, crosshair_mc);

//the center would be the player's character and crosshair_mc is just set to the mouse position. DistanceBetweenHorizontal + vertical just calculates the distance obviously.

function DistanceBetweenHorizontal(mc1, mc2){
var dx = mc2._x - mc1._x;
return(dx);
}
function DistanceBetweenVertical(mc1, mc2){
var dy = mc2._y - mc1._y;
return(dy);
}

Looks like you need to figure in the mc's x/y location when you do myMatrix.translate.

thanks for the advice! I switched the code around a bit and this seems to work OK. I don't know yet if it'll work with my scroller function though. Thanks again!
I'm working on a game called ¡Ya Basta! which can be found at http://www.sebazistan.com and comments are appreciated. Basically I want it not to reinvent the side scroller but to do EVERYTHING all the best side scrollers do. Anybody who is curious-- I'm happy to share code.

replace this in the actionscript above:

onMouseDown = function () {
var myMatrix:Matrix = new Matrix ();
myMatrix.translate (this._xmouse-my_mc._x, this._ymouse-my_mc._y);
myBmp.draw (hole_mc, myMatrix, myCT, "erase");
};
onEnterFrame = function () {
//get the pixels
if (myBmp.getPixel (dot._x-my_mc._x, dot._y-my_mc._y + 1) == 0) {
dot._y+=gravity;
}
my_mc._x++
dot._x++
};

[sebazistan]

Well, this seems to work fine!! Thanks again!
