yeah u guys remember in MegaMan X2, X could dash and do a air dash? I want to know how to do that so if anyone can help me out?
Could you probably post a video of what exactly you are trying to create? 
Most things in MegaMan were made with sprites. Some effects can also be done with particle systems (e.g the “fog” behind him when he moves fast -> just an ordinary particle system with a low spawn rate)
well what I want is my character to do a air dash/ dash like megaman x. I only want him to move like megaman x
