Mr. Sheep, thank you, you've solved my problem

Changing direction from 270 to direction stopped the bouncing but made the character stick to the ceiling, and then checking for an empty space above the character made it so he could move. Thanks!

Well of course that will happen if you simply uncheck solid. I meant more like program things to work without making it solid but you might need to change things.

Anyway, I can't really help. I am too confused with the Dnd. If it wasn't in Dnd I would have been able to help much easier. I've gotten it to work slightly but its glitchy.

Sorry

Don't worry about it, I still appreciate the help  

I'm a bit confused about the whole not making anything solid thing. Could you explain how I would do that? I've tried it, along with changing all the checks for solid objects and the whole, 'move into contact with solid/all objects' thing,  but my character just seems to sink through the floor.

I tried making only the ceiling non-solid, and that helped a bit. The character is still shaking up and down but now he's able to walk through those tight passages while pressing up, instead of getting stuck and not being able to move. But that's imperfect because if I come at a ceiling from the side I just sink through it instead of coming into contact with it.

I also can't seem to make the turning off gravity while swimming thing work with my code... have you had any success?

One thing I've tried that seems to influence it is fiddling with the 'move to contact' action within the collision event between the block and character. If I change the 'maximum' number, the shaking seems to be influenced. I can't find a number that will make it go away, but I can make the shaking more compact. I'm not sure what that whole maximum thing means, the game maker manual doesn't explain it well enough for me and I can't find any outside resources that explain it any better.

Its definitely a simple fix, I'll keep thinking but hopefully someone with a better knowledge of platforming in GM will chime in. I would suggest not making the ceiling solid (or have any solids for that matter) and I would suggest removing gravity when you are actually swimming.

Oh wow. Hah that's why I come here, I would have never thought of either of those things. Thanks, I'll try it out!

Yup, its in dnd which would explain why changing methods would be extra hard for you. Also it makes things a bit harder to figure out whats going on and to help. I've never done an extensive platforming game either. I've tried some things that haven't worked yet

Ah. Well thank you very much for trying, please keep at it if you can. Hah underwater caves were gonna be a big thing in the game and I'll be really bummed if I can't do them because of this glitch... do you know of any other avenues I might go to to find a solution?
