Randomization/Game

programming flash

Hey all, I have a small game i’m coding, and basically I have it so that I can spawn powerups every time an enemy is killed - the powerup spawns and bounces around the stage until it’s picked up. I want it to have a chance of spawn (let’s say 1/10). I can’t seem to achieve this. I’ve tried setting a random number and running a check for it, but it doesn’t seem to read the random number.

Inside the explode() function, an explosion graphic is played, the ship is removed from the scene, and a powerup is spawned.

Can anyone help? I’ve attached the code.

class EnemyShip extends MovieClip
{
	var speed;
	var shootTimer;
	
	function onLoad()
	{
		_y = -93;
		_x = Math.random()*200+50;
		speed = Math.random()*5+5;
		shootTimer = 0;
		
	}
	function onEnterFrame()
	{		
		_y += speed;

		if(_y > 500)
			{
				this.removeMovieClip();
			}
		if(this.hitTest(_root.ship))
		{
				if(_root.ship.shield._visible == false)
				{
					_root.ship.updateHealth(-20);
				}
			explode();
		}
		shootTimer += 1;

		if(shootTimer > 30)
		{
			shootTimer = 0;
			var missile = _root.attachMovie("EnemyMissile","EnemyMissile" + _root.getNextHighestDepth(),_root.getNextHighestDepth());
			missile._x = _x;
			missile._y = _y;
		}
		
		
	}
	function explode()
	{
		var reward = _root.attachMovie("RewardPoints","RewardPoints" + _root.getNextHighestDepth(),_root.getNextHighestDepth());
		reward._x = _x;
		reward._y = _y;
		reward.field.text = 50;
				
		var explosion = _root.attachMovie("Explosion","Explosion" + _root.getNextHighestDepth(),_root.getNextHighestDepth());
		explosion._x = _x;
		explosion._y = _y;
		this.removeMovieClip();
		_root.ship.updateScore(50);
		
		var powerup = _root.attachMovie("PowerUp","PowerUp" + _root.getNextHighestDepth(),_root.getNextHighestDepth());
		powerup._x = explosion._x;
		powerup._y = explosion._y;
	}
	function takeDamage()
	{
		explode();
	}
}
