Physics and Collision detection

for the physics and collision detection I used "Rapier" a physics engine to handle it for me, I just have to tell the engine what entities I want to be effected by physics.

However I'm having a bit of an issue,
I'm making a top down 2d game and I can't seem to find the proper way of doing that, I made the player and the boxes dynamic rigid bodies so the player can push the boxes, and I hacked in a way to make that work, but for some reason when I make the boxes a fixed rigid body the collider doesn't stop the player from going inside the box when moving at a low velocity, I'm trying to search for a proper way to do it, but still didn't find anything useful.

I searched for how it works in the unity game engine, so I could maybe get a sense of how rigid bodies work, but I couldn't find a solution to my problem yet

How are you adding velocity to your player character?

How are you adding velocity to your player character?

Hey, sorry for not replying!, I never got any comments on my issues before, so didn't expect to get one!

however, I got it working by adding the velocity by getting the delta of x and y then add it to a Vec2 and then making that equal the linear velocity for the player

    let x_axis = -(left as i8) + right as i8;
    let y_axis = -(down as i8) + up as i8;

    let mut move_delta = Vec2::new(x_axis as f32, y_axis as f32);
    if move_delta != Vec2::ZERO {
        move_delta /= move_delta.length();
    }

    // Update the velocity on the rigid_body_component,
    // the bevy_rapier plugin will update the Sprite transform.
    rb_vels.linvel = move_delta * player.velocity;

if you have a better solution in mind please don't hesitate to teach me!

also thanks for replying to my issue!
