Neither 'On Collision' nor 'Overlaps at offset' works with moving platform

Hey all,

It seems neither 'On Collision' nor 'Overlaps at offset' will work when a platformer object hits a solid object while standing on a moving platform.

I made a very simple sample project to demonstrate - clicking on the blue block makes it move left, but when the player collides with the purple block the events do not trigger.

Is this a bug or am I doing something wrong here?

Thanks in advance!

I don't think using 1 | -1 works here, it works if you split it up. I don't think Construct particularely likes | in many cases. Now as to why it doesn't detect a collision... no idea, but I'd guess it has someting to do with the inner workings of the platformer behavior? The platformer behavior also has a condition (is by wall) for checking this btw.

Ah interesting, splitting it out does indeed work. I should have tried it :)

I'll do that moving forward. Thanks!
