Whats goin on speed prob

Hi ..

Well decided that id try and make a fast little game, just to get my head round all this new OO and syntax stuff. this project when complete will be open to the community in the hope that it will help some other New ppl pick up the language easier.

Anyway onto the problem, In my bullet type I have the update method, all this really does is change the Y field of a bullet and reduce by speed to move the bullet up the screen.

But when I fire 2 bullets they move at twice the speed, and so on as I fire even more.

	Pocket Space Invaders
	By Paul Grayston (Team Rebellion Software)
	
	The Aim of this project is to create a small
	Space Invaders game using some of the new
	features found in blitz Max.
	
	This is to help me and others like me in the
	process of moving from blitz 3d to blitz max.
	
	I will do what I can to make sure as much of 
	this source is commented as possible to make
	things as clear as possible.

You are going over the list of bullets recursively (or is it exponentially? :) )

For bullets = EachIn BulletList
-> Goes to function bullets.update()
-> which does
-> For bullets = eachin BulletsList
-> add speed to this bullet
-> Next
Next

OMG so I am.

Dood I would have been here till 4AM trying to track that down lol.(2AM now)

thanks.
