changing spell color

is there anyway to change the color of lets say firebolt? so from like a redish to a green? (without making skin)

Well If You want it to look like the spell you would have to skin it, but if you want any old green bolt just change the projectile's model in the ability editor. Im positive that there are at least 2 or 3 green projectiles...like the one from a metamorphosed demon hunter. Another alternative would be to make a triggered spell and change the model color throught the animation - change units vertex coloring <<< not exact wording but you get the point.

If you do that you must use a dummy unit, which should work unfortunately you will run into the problem of the hardcoded max unit speed. Other than the speed it should work and be much more versitile.

That depends. If the Firebolt's flaming-ness is generated from a particle emitter, then changing its color won't make any difference.

hes got a point there so if as i said if it needs to be perfectly like the premade version you would have to skin the bolt and then skin the texture for the particle, but i believe all methods were covered and what you want is going to ultimately determine the method u need.

The Green Dragon's projectile is very similar.
