Need help getting collisions with walls working

[forestherd]

Hello!

I'm sorry if this question has been asked here before. Unfortunately I did not find anything relevant on this subject (or at least could not apply it to my case) and so I'm here making a post about it.

Namely I'm making a small top-down game and I want to be able to place down walls in the scene. I'm currently approaching the issue of collision from a Game Maker Studio perspective and moving my objects until a collision is found. Unfortunately my current approach doesn't seem to be working and I'm not even convinced it is within the capabilities of Phaser 3. Currently my moving gameobject with a circular collision box gets stuck in the sides of the wall. Here is the code I have right now for handling movement with wall collisions. I'm using arcade physics. It is run inside my moving gameobjects' update function:

    public move(vector: Vector2): void {
        let length = vector.length();
        vector = vector.normalize().scale(Math.min(this.maxMovement, length));
        let total = vector.x;
        while (total != 0) {
            let amount = Math.min(Math.abs(total), 1) * Math.sign(total);
            this.x += amount;
            let collision = this.scene.physics.overlap(this, this.castScene.wallGroup);
            if (collision) {
                this.x -= amount;
                total = 0;
                this.movement.x = 0;
                break;
            }
            total -= amount;
        }
        total = vector.y;
        while (total != 0) {
            let amount = Math.min(Math.abs(total), 1) * Math.sign(total);
            this.y += amount;
            let collision = this.scene.physics.overlap(this, this.castScene.wallGroup);
            if (collision) {
                this.y -= amount;
                total = 0;
                this.movement.y = 0;
                break;
            }
            total -= amount;
        }
    }

My current assumption is that scene.physics.overlap does return the proper value every time I update the x or y position of the object. If this is the case, what could I do to work around this? What other approach could I try out? Is there a way I can handle collision such that I can still define how many units per step the object takes?

Thank you in advance!
