Move character in world space

I have a third person character in a VR project similar to Moss which started life as the third person c++ starter project.

I have him moving around and jumping as well as swinging a sword etc. but now I’m working on climbing up a cliff.

I have the ability to jump up and grab a ledge and then climb up as well as move left and right while hanging onto the ledge, but I’m having some problems with the ledge movement.

For ledge detection I have some collision object set on the ledge and a small spherical collider on my main character just in front of his face. When this collider touches a ledge collider he grabs hold of the ledge. At this point I set the movement mode to EMovementMode::MOVE_Flying and snap him to the closest point on the ledge collider.

Now I can move him left and right until he gets to the edge of the collider. I do this by looking at the colliders width and calculate how far he has moved. Each collider has a variable which stores the collider on the right and left so I can connect a string of colliders together and make curved ledges.

This all works except that when I attach to a ledge, I snap to the closest point and this makes the movement around a curved cliff look jerky as he doesn’t rotate around the curve smoothly but instead pops into a new rotation as he passes between the colliders.

To get around this I thought I would remove the snapping rotation and slowly rotate him to match the same rotation as the ledge collider, however I can’t get him to move down the ledge without snapping his rotation because I’m using;

AddMovementInput(GetActorRightVector(), Value);

The docs say AddMovementInput uses a world space vector, but if I pass in the ledge colliders RightVector he doesn’t follow it. I then tried just forcing a vector of (0 1 0) thinking it would move him in world space down the Y axis, but instead he moved locally right and left?

Can anyone tell me how to move a character in a world space vector ignoring his rotation?

I also uploaded a example video showing the movement problem as well as the colliders I have before the game starts.

AddMovementInput does use a world space vector. FVector(0.f, 1.f, 0.f) is the World Space right vector. Your youtube video is set to private.

Hard to say what is going on but one thing I’d suggest is to also set the acceleration value to a very high number so that changes in velocity are applied instantly.

Thanks for the reply and letting me know I messed up the video. I had it set to publish when ready, but it never published itself. I’ve fixed it now.

I thought it was world space after looking around online, but I can’t get it to work. As this is a character component, I wonder if I have a setting messing with it, something like rotate forward while moving.

I will look at this again over the weekend, for now I’ve moved onto something else, starting the inventory system.
