How do I get knockback in the opposite direction of the mouse?

UnknownUser

I'm new to Godot and have only been using it for about 4 days.

Currently I have a Game scene, a Player scene and a LaserBeam scene. The LaserBeam fires a laser in the direction of the mouse.

I would like to give the player a constant knockback effect while the laser is being fired (the knockback being in the opposite direction of the mouse), but I'm not sure how to do that. I imagine the code for this would be in GameScene.gd

In the Main Game scene the Player instance is a child of the GameScene root and the LaserBeam instance is a child of the Player.

The code for the Player Scene is:

The code for the LaserBeam scene is:

I am open to any suggestions and changes required in my code.

Any help would be greatly appreciated!

well as you already know the direction of the laserbeam, your knockback direction would just be knockback_direction = -beam_direction.

Then you need to connect a signal from your laserBeam and emit iunside your _input function.

in the playerscri[pt add a knockback(direction: Vector2): void function which you trigger on the signal. This function should mopve your player in the given direction a given amount. For that you have multiple options: 1. set a boolean variable and do the movement inside your _physics_process 2. tween your player position to a precalculated position target_position = position + knockback_direction.normalized() * distance 3. make the knockback only visually by moving the spritew but not the body itself. For that an AnimationPlayer would be useful
