How To Create One Way Platforms

[TGSP]

So, let me just start off by saying that I'm a beginner in game maker. Though I do know some basic gml coding. In the game I'm currently working on I need to make one way platforms (platforms that I can jump through from the bottom but when on top I don't fall back through). How exactly would I go about doing this? What's the most simplistic way of going about such a matter? I've been searching for hours on youtube and on forums all over the internet but considering my current physics and movements I can't find a way to make one way platforms feasible.

Well, I'm not much of an expert on the subject myself, but i can give you the most simplistic way to do this:

//This code is written assuming that your player lands on SOLID objects

//In the STEP event: (of obj_platform)
if(obj_player.y < y){
    //makes the platform object the opposite of solid
    object_set_solid(obj_player,false);
}else{
    //makes the platform object solid
    object_set_solid(obj_player,true);
}

I believe that's it! Hope this works for you!!!!!!!!!

Hi friends.

It would be better if you are more specific with your physics and movements.

Hope you find it useful.

Thank you for your replies I was actually able to figure out how to get it working by following rexfurry's tutorial on youtube
