[SOLVED] How to toggle a variable

So I was trying to make a script so that if a click and grappling == false it turns it on and vice versa but i realize that since it reads from up to down it’s going to just go from on to back off.

script:

var GrapplingHook = pc.createScript('grapplingHook');

GrapplingHook.attributes.add("camera",{
    type: 'entity',
})
GrapplingHook.attributes.add("player",{
    type: 'entity',
})
GrapplingHook.attributes.add("point",{
    type: 'entity',
})
// initialize code called once per entity
GrapplingHook.prototype.initialize = function() {
    this.screenCenterX = this.app.graphicsDevice.width / 2;
    this.screenCenterY = this.app.graphicsDevice.height / 2;
    this.hidgePoint = null;


};

// update code called every frame
GrapplingHook.prototype.update = function(dt) {

    this.start = this.camera.camera.screenToWorld(this.screenCenterX, this.screenCenterY, this.camera.camera.nearClip);
    this.end = this.camera.camera.screenToWorld(this.screenCenterX, this.screenCenterY, this.camera.camera.farClip);
    this.grappling = false;
    this.doRaycast()
 
    if (this.app.mouse.wasReleased(pc.MOUSEBUTTON_LEFT)){
        console.log('Pressed')
        if(this.result){
        this.hidgePoint = this.result.point
        this.ray = new pc.Ray(this.start, this.hidgePoint);
        this.direction = new pc.Vec3().copy(this.hidgePoint).sub(this.start).normalize();
        // now you can use the direction and scale it to become a force
        this.power = new pc.Vec3().copy(this.direction).scale(10000);
        if (this.grappling == false){
            this.grappling = true
            console.log("on")

        }
        }
        if (this.grappling == true){
            this.grappling = false
            console.log('off')
        }
        
        
    }
    // actually do the thing
    if (this.grappling == true){
        this.app.drawLine(this.start, this.hidgePoint, pc.Color.RED, true);
        this.player.rigidbody.applyForce(this.power)
        console.log("Grappling")
     }
};

GrapplingHook.prototype.doRaycast = function() {
    this.result = this.app.systems.rigidbody.raycastFirst(this.start, this.end);
}



// swap method called for script hot-reloading
// inherit your script state here
// GrapplingHook.prototype.swap = function(old) { };

Hi @Literally_Kirby!

Do you mean something like this?

// toggle between true and false
this.grappling = !this.grappling;

bro i swear it isnt working
