I have been trying for days now to create a moving platform that has a hole in it that the player can jump through and land on the platform, but he can still fall down throught the hole from above.
I can do it ok if the platform has movable ticked but anything above lands on the platform it makes it fall downwards with the item.
Pleas can someone help it is driving me nuts. cheers

    Can you post a video showing what's happening? You might just need to set the platform's restitution to zero and make its fixed rotation checked.

    I have attached the file to see if anyone can help.
    The player seems to be able to jump through the platform at one end and after a while eventually falls down.
    Please someone help

    Yeah, that's a strange one. There's a hero actor that falls (accelerate 2000 @ 270°) onto a moving platform (constrain linear velocity x to 100). The hero can move left and right along the platform, but at one end of the platform the hero just falls right through it as if it's not there. Similarly, jumping under the same platform causes the hero to bump up against it except at the end, where the hero can just jump up through it.

    So far, I'm stumped. Maybe someone else can help...

    Sometimes, when I have a problem, I completely start over and most if the time it's fixed

    True, but I was able to reproduce this effect in a new project file.

    The reproduction of the problem? Sure. :P I didn't keep it, but here's another version I just made: https://www.dropbox.com/s/igrj74lwagyyvvr/non-collide.zip. The problem's not as evident, but it's still there. If you move left (left arrow key) along the platform, you eventually fall through the platform actor (before you reach the "hole").

    Hey guys I'm not sure if this will work but I had a idea I can't test it out because I am nowhere near my computer so I thought I would just post it here anyways maybe if you try this.

    For the platform with the hole in it try leaving the platform blank and creating 2 actors in both of them put a collide with the hero behavior then put them both on the screen on the left and right side of the platform but leave a gap in the middle that might work so the hero can go left and right without falling but can fall through the gap.

    Sorry if it doesn't work just an idea that popped through my head.

    Oh and to get the player to jump through the hole and land on top without falling through @tshirtbooth had created a tutorial for it if it not him I'm sorry to who created it. Just make a new a tor put it in the gap of the two actors and I will find Tshirtbooth tutorial for you.

    The problem is having "Wrap X" turned on in the scene. Its because the platform is on the right -- no wait-- its wrapped to the left -- no wait -- its on the right -- no wait -- its wrapped to the left.

    @Bilzo12 is correct. If you uncheck wrap X, and If you place two copies of the platform actor so that the correct gap is formed then the problem goes away.

    To get the platforms to wrap, use a rule in the platform:

    When self.Position.X > (game.Screen.Size.Width +( self.Size.Width/2))
    -- Change Attribute: self.Position.X To: -( self.Size.Width/2)

    That should fix it!

    Did you try @RThurman's advice about turning off wrap and using a rule to wrap the platform actor based on its x position?
