Check if the player is grounded code with bump.lua

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.
