2d ai move on stair

HELLO I NEED TO ASK HOW CAN I LET AI USE THE STAIR IN 2D SPACE

No reason to yell :wink:

Not sure what you mean, there’s no “allow AI to use stairs” switch. And it all depends on your navigation setup. Are you using navmesh? Are you using navigation-less (straight-line) paths? It may boil down to setting MaxStepHeight in the character’s movement component.

Cheers,
