Collisions issue/problem/WTF?

Why does this moving static object cause my player to slide all the way to its bottom in 1 frame? I just want it to push it along.

What do you mean moving and static, those are two opposite things? In general, physics work best when you let the physics engine control everything. You should never move a StaticBody ever (that is the definition of being static). If you need movement, use the physics functions to add velocity or spin to get the movement, this will be simulated by the engine and work.

Thanks a lot!

Yeah I know static is supposed to be static but when I made it a rigid body my player was able to slide it around. Maybe it just needed to be way heavier?

Is there a way to use the animationplayer to move the wall like you see in the video or should i do it some other way, like create a pin joint, make the wall heavy, and add an impulse to it?

Yes, you can use the AnimationPlayer. I forget the settings, but I believe you want a RigidBody in the Static mode or something like that. And there is a check box to Sync to Physics. That should work.

That pretty much worked but now I have the issue of the wall being just kind of weak. My player (kinematic body) can push it even though i made the weight very high. I am unsure how to make the wall just keep moving no matter what, as if its a giant heavy wall that can push my player. I am applying angular momentum of 2 continuously using animation player, until I take it to 0 in 8 seconds.

How do you think I should keep the wall moving no matter what? I want it to move until closed and not be so weak the player can move it so easily.

Hmm when I put the wall to static mode (but rigidbody) it lets me change its rotation in animation player which is cool. My ship doesn't move it, I like that also. But when the player collides with it or it collides with player it does that stupid slide to the end of the collider thing.

I can't believe I'm the first person to have a moving wall move a player, there must be a standard way to do this.

Doesn't seem like changing the rigidbody's rotation angle is the right thing to do, it appears moves the collider in front of the sprite and it seems to stretch out the object as well, making it taller as it rotates. so weird.

Changing a rigid body position and rotation will always result in glitches unless once at the start of the game or something. You can try adding a constant angular momentum.
