checking for walkable areas

[stepsoversnails]

I can't figure out a script that simply checks if there is a certain amount of walkable area in front of a character.
i'd really love some help, thanks!

I don't quite get your question, what do you mean by walkable area in front of a certain character?
Are you referring to walk-behinds instead?

it's okay i got it.
aha.
sorry for that.

Code: ags

if (GetWalkableAreaAt(cEgo.x - 30, cEgo.y - 0) == 0){
   Display ("There's not enough room.");
}
else {
