Am trying to figure out the best way to do bullets and be able to update a score and actually get the x and y coordinate of the enemy ship I kill. Currently I have a fire_bullet function that references a bullet projectile symbol and I do the hit object test there. If I do the hit test in the main program loop it only registers some of the bullets but if I do the test in the projectile symbol I can send back certain info to the main program. Like the x and y coordinate of the enemy ship. Here is my current code.
function fireBullet(event:KeyboardEvent):void
{
if (event.keyCode == 13)
{
var angle:Number = ship1.rotation;
angle = angle*Math.PI/180;
clip = new Projectile();
addChild(clip)
laz.play()
clip.x = ship1.x+nose*Math.cos(angle);
clip.y = ship1.y+nose*Math.sin(angle);
//trace(angle);
clip.xmov = speed*Math.cos(angle);
clip.ymov = speed*Math.sin(angle);
clipList[clickCount] = clip;
clickCount++
shotCount ++;
clip.explo = explo
//clip.wavecount
clip.alien = alienList[waveCount]//List[waveCount]
}
}
I have a clipList[clickCount] array i was going to try to use in the main program to test for hits but could not get that working.
Here's the code for the projectile symbol.
addEventListener(Event.ENTER_FRAME, moveBullet)
var i:int = 0
function moveBullet(event:Event):void
{
this.x += this.xmov;
this.y += this.ymov;
if (this.alien != null)
if (this.hitTestObject(this.alien))
{
//trace("Hit")
this.alien.gotoAndPlay(6)
this.explo.play()
i++
//removeChild(this)
if (i % 4 == 0)
{
//alienList[waveCount].rotation+=180
this.alien.rotation = 0
this.alien.x = 10000000
this.alien.y = 200
}
}
}
The current way I deal with scoring is by sending the alien to this.alien.x = 10000000 and then thes code that sets next_wave to false which launches the wave function in the main code and setting jack to true increments the score.
if (alienList[waveCount].x >= 5000)
{
//removeChild(alien)
jack = true
nextWave = false
waveCount++
}
function wave():void
{
kill = false
attack = 40
l++
if (l % 6 == 0)
{
if (jack==true)
{
removeChild(alien)
jack = false
score += 10
}
}
i++
if (i % 48 == 0)
{
addChild(alien)
n = Math.random() * (foodList.length - 1) //random food for enemy to go after
//trace ("n",n, "foodList.length",foodList.length)
alienList[waveCount1] = alien;
attack = Math.random()* 40
//trace("attack",attack)
if( attack <= 5)//remember it is 10
{
kill = true
}
m = Math.random()* 20
if( m < 10)
{
//trace("mupper",m)
alienList[waveCount1].rotation = 0//reset to down
alienList[waveCount1].y = 25
alienList[waveCount1].x = Math.random() * (stage.stageWidth - alienList[waveCount].width)
}
else
{
//trace("mlower",m)
alienList[waveCount1].rotation = 0 //reset to down
alienList[waveCount1].rotation +=180 // flip to up
alienList[waveCount1].y = 310
alienList[waveCount1].x = Math.random() * (stage.stageWidth - alienList[waveCount].width)
}
waveCount1++
nextWave = true
}
}
So this works but I want to change it because I am having some timing issues. I currently have the alienList[waveCount] (alien symbol) calling a gotoAndPlay(6) that has the explosion in it. I want to separate the explosion from the alien symbol and be able to take the enemy x and y coordinate and kill the enemyShip right away and have an explosion symbol be right at the x and y coordinate of the removeChild(alien) with something like this:
alienList[waveCount].x = tempx
alienList[waveCount].y= tempy
explosion.x = tempx
explosion.y = tempy
removeChild(alien)
I wish you could have global variables in the symbols. Or that _root. worked. I read about that but I guess that was a previous version of actionscript. Any help in this matter will be appreciated. Thanks.
