It means the platformer speed is not zero so yeah it includes falling and jumping.
"On moved" is a trigger that fires once when the sprite starts moving. "Is moving" is true every frame while the sprite is moving.
thank you so much i understand it now.
I have another question hope can get answer here then i don't have to write a new post.
How to "compare X speed"? i can only found "compare speed" in actions, this include x and y, but i only need x.
if its not available, how can i do it with variable, such as differencing x coordinate on every tick?
