I am currently working on having a fire ball fly across the screen. The fire ball's model is a sphere that has a tail thats a cone. I can get it so it will shoot in the correct direction. The problem is I can not get the fire ball to rotate so that the tail is pointing in the right direction. Does anyone have any suggestions?

thanks

Use vec_to_angle for that. If "vSpeed" is the speed vector of your fireball, set its angle by

vec_to_angle(my.pan,vSpeed);

Thanks a lot jcl, it worked
