what is a "jump"? do wall jumps count? bouncing on goombas? going on trampolines? just need some clarifications

im not sure, but my understanding is that it is an up press, so jumping onto a goomba and have it bounce you shldnt count, and holding up to bounce high shldnt, but doing a low jump then repressing jump after touching the goomba should count as a jump

Mods?
