Ok what i gotta do if to make some airplanes bomb over a city but i don't know how to create an explosion i already set the bombs on the plane and cross the city but i dont know what to do know please help thank you very much
Depends on what kind of explosion you want. You can make a 3-d one that looks sorta like an explosion by setting a sphere's texture to that of one of the fire objects, then having it increase in size quickly when a bomb goes off to look like an explosion, or you can have a 2-d one that looks like a real explosion , but you have to make it face the camera whenever it appears to maintain the illusion that it's 3d (like the smoke effect in the Web Gallery).
Well, it also depends where you want yoru explosions. Ive made games where bombs are just going off in the air, its my first Modern Warfare game i made. The explosions are just going off
