2D Motion Trails?

by CharlesL · in iTorque 2D · 02/04/2013 (3:03 pm) · 3 replies

Can someone tell me how to make motion trails (like in fruit ninja and angry birds)? I couldn't make a particle system the worked, even though I set it on maximum quantity.

If the only way to do it is via particles, is there a way to generate more?

Thanks,
- Charles

Particles are very expensive to use in terms of performance. My advice is to make an animation of your motion trails and use that - you set the animation to play over e.g. 5 seconds s you will see your particles decay/fade etc.

Another way is to use the old 'snake' trick.

As you move the object, stamp out the trail and for for each stamp schedule a timer, passing in a reference to the piece of the trail. When the timer expires you just fade it out.

What do you mean by saying to make an animation of the trials? Do you mean to animate the character sprite?

What function is it that would stamp out a trail, I didn't realize that there was such a function?

Anyway, Thanks :D

By stamp, I mean clone the sprite and leave it in a static position and then fade it. Your original sprite keeps moving and the cloned sprites just fade away, giving the appearance of motion trails.
