controlling player fire in space invaders game

[gooberachi]

Hi all,

I'm working through an online tutorial on Space Invaders in Flash MX 2004.

I've got the player craft under mouse control. What I don't like about the game is that you can fire as rapidly as you wan't, though the number of bullets is limited. You can change this limit in the variable - I would rather have it though that you can only fire according to a certain interval - a bullet every second, or half second for example.

Here is the code:

// when the mouse cliks
onClipEvent(mouseDown)
{
// duplicate the bullet mc
_root.bullet.duplicateMovieClip("bullet"+bulletNum ,bulletNum);
// set the coords to the mouse clik
eval("_root.bullet" + bulletNum)._x = this._x;
eval("_root.bullet" + bulletNum)._y = this._y;
// increment the bullet number
bulletNum++;
// if more than 50 bullets , start again at 0
if(bulletNum>50)
bulletNum = 0;
}

Anyone have any code that could be used for this, or ideas on how I could modify the above?

regards,

g

Howdy, you might be able to use a variable. You cold have it increase like your bulletNum variable and then after it hits a certain number say 5 it would stop shooting and after you let go of the button it goes back to 0.
