Check if the player is grounded code with bump.lua

[Crono]

Beginner here. I'm trying to get the values of normal.y in the table cols in bump, to then change the variable self.onGround, but I just can't do that. Either the code is wrong or the logic is, but I don't know why. This is the code I think was supposed to work:

Code: Select all

for i=1, len do
	if cols[i].normal.y == -1 then
		self.onGround = true
		end

Try checking if the normal is 1 instead or 0, one of those should work, I think.

If I do that the variable never gets true.

Is the variable ever true when you check for -1?
If anything you can just check if there is a block 1 px under the player.

I had the code for this and I remember that the value was -1, but I deleted it because I'm and idiot. I'm already using the 1 pixel for now.
