Falling Through Platforms

[dsilvers]

I've started using the Custom Platform Movement extension for a new game, but I am having some major collision issues. Mainly, my sprites keeps falling through the backdrop. The backdrop is set to Platform and I've followed the tutorial to the T.

PMO: Set Object to Active 1
PMO Test of Obstacle Overlap, Active 1 is overlapping a backdrop: Selected Object Overlaps an Obstacle

Unfortunately he falls right through it. I'm using the backdrop as the ground and it's just one long rectangle. Setting the movement to Stop and Bounce hasn't done anything either; just slowed the fall.

What am I forgetting?

Use "Test For Jump Through Platform Overlap" if they're set as Platforms

Using the movement options on the active won't have any effect, they're for the inbuilt movements.
