Particles tutorial question

Hi,

Great tutorials here, I just finished the particles tutorial and using it in my space shooter game.

When my missile hits the target, it kills it and draws the particle explosion, however the particles will keep drawing until i kill another target.

I have tried to change the TTL variable, the update methods and still cant get out of the loop.

What I want to happen is to hit the target, draw the explosion and then for the explosion to die.

Have been looking around and am thinking I may need another few "time" variables like:

birthTime

maxAge and so on.

Any pointers would be a help.

Thanks all.

Hi!

I had a similar problem and all i did is adding a public "Active" boolean variable in the particle engine and in the update void i do not create new particles if not active. From there you can put the active variable to true or false wherever you see fit.

hope that help!

Go look at Reimers 2D tutorials for xna. it perfectly describes what you want in the last few chapters of the tutorial.

You need to change the particle emitter's location. So maybe make a timer and then move the location after a set amount of time to off screen, or just stop drawing them.
