Any suggestions for how to make these?
I’ve made one, but mine is a little too performance intensive and it is also missing some of the cooler effects.
I used a white tube, and an updatable mesh. Right when a bullet is fired I create this tube along a path, and then I very quickly collapse the tube from the source the point of impact. Even though on the first frame its just a long tube from A to B, the eye seems to perceive as motion thanks to how it collapses.
So that was cool, but making a whole lot of these updatable tube meshes is a little too much on the lowest end machine that I’m targeting (it almost works though). Also, I want to try making the smoke trail after effect which is popular in several games now. It’s a bullet tracer that starts hot white/yellow, and then rapidly fades into being a little wispy smoke animation, and the whole thing is gone in like 100 ms. I think there may be another important part of the effect, which is that the fading from white to smokey occurs gradually (well, pretty fast) along the length of the tracer – like my collapsing tube that creates the illusion of a bullet traveling along the path.
So I was wondering if anyone knew of approaches for making these? Tubes? Ribbons? Animated sprite on some other mesh? Billboards?
I’ll be experimenting, but would appreciate tips/ideas.
