forestherd Posted April 22, 2020 Report Share Posted April 22, 2020 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! Link to comment Share on other sites More sharing options...
