Make a sprite follow a spline path


Recommended Posts

I am a Phaser beginner.

I have created a spline path as per the example given here: http://phaser.io/examples/v3/view/paths/curves/spline-curve

I want to make an image/ sprite follow the spline path with variable acceleration given by the user. How do I do this?


create() {
        //loop below statements for each car
        this.car = this.add.image(50, 400, 'car'); //TODO: make a car class
        this.car.rotation = Math.PI / 2;
        this.track = new Curves.Spline(this.trackPath);
        this.path = { t: 0, vec: new PhaserMath.Vector2() };
    update() {
        this.graphics.lineStyle(5, 0x5f0f40, 1);
        this.track.draw(this.graphics, 64);
        this.track.getPoint(this.path.t, this.path.vec);
        this.car.x = this.path.vec.x;
        this.car.y = this.path.vec.y;
        this.graphics.fillStyle(0xff0000, 1);
        this.graphics.fillCircle(this.path.vec.x, this.path.vec.y, 8);
