Player falls through platform?

Hey everyone, quick question about jump-thru behaviour.

I used Ashley's manual to get to the point where my player can jump up through platforms and land on them. However, often my player will jump through the platform, fall back through it and land on the ground instead of the platform.

Does anyone have an idea why this is happening?

It could be many things, such as depth of platform, collision polygon errors, etc.

The quickest and easiest way of getting quick and effective assistance is to post a simplified .capx with the problem, so that people can instantly see and understand the issue. Without it, it's just guesswork.

zenox98 Thanks, it seems that by switching from jump-thru to solid behavior in my platforms while the player is falling, the problem is eradicated.
