So I requested help on this old project back in the original GM forum and no help but I have come back to it trying new things.
Off and on for a few years I have been trying to make a random generated endless runner using slopes. I can get the slopes to work fine on their own in many different ways. I got the level to randomly generate and sync the slopes and then move them to the left like a runner often does....On it's own.
When you put the two together though, ground moving to the left with a slope coming at the player, upon collision, the ground/solid objects/slopes whatever, they move. If I jump and land on them they shift a little. When they come for the player, instead of the player rising and falling with the slopes, he pushes those objects like a bulldozer across the screen stacking them on top of each other.
I'm not going to post the original code here because I forgot how most of that giant bunch of code works atm but recently editing Strawbry_jam's Part 2 code from https://forum.yoyogames.com/index.php?threads/generic-platformer.1090/
Found here: https://drive.google.com/file/d/0B-XGa2C_e2NSNTd5cjZ6aFp3RTQ/view?usp=sharing
I was able to do get it to do what mine does, granted I just made the controls move the ground instead of the player.

Then I added a step even in the slopes and ground so I could force the ground to move with the L and R arrow keys instead of the player. FYI Up arrow makes player jump still so you can see that crash as well.

Any help would be greatly appreciated. Not being able to figure this one out is why I keep stepping away from GameMaker.
