Question about graphics and anchors

[Ninjadoodle]

Hi @enpu

I'm making a timer bar using drawRect, and I'm wondering if you can set anchor points?

When I put the graphic inside the original canvas size, it tweens as if the anchor was at (0,0), however when I move the graphics slightly outside the canvas, it looks like the anchor is always at (0,0) of the canvas.

Thank you for your help!

Yes you can set anchor points in Graphics.

I'm not sure what you mean by that or what actually is the issue?

@enpu - it seems that wherever I put the graphic on the stage, it tweens its scale from the ‘stages’ (0, 0) position.

This could very well be something I might be doing wrong, I just can’t seem to get it working correctly.

Hi @enpu

Unless I'm doing this wrong there is something up with graphics and tweening.

I've setup a bar png and tried tweening its scale and that works perfectly fine.

When I try tweening a graphic tho, the tweening / anchors seem all out of whack.

This is my graphics setup code.

this.bar = new game.Graphics();
this.bar.fillColor = '#ff0000';
this.bar.drawRect(320, 320, 480, 100);
this.bar.addTo(game.scene.fg);

game.Tween.add(this.bar.scale, {
    x: 0
}, 20000, {
    easing: 'Linear.None'
}).start();

The bar scales as if it anchor point was set somewhere else but its top left corner .

Am I missing something/ doing something wrong here?

Thanks again

You should draw your rectangle at position 0,0 and then move the whole graphics object to the position 320,320.

Position of Graphics object and the position of shape is different thing, shapes have also positions because Graphics object can contain multiple shapes.

this.bar.drawRect(0, 0, 480, 100);
this.bar.position.set(320, 320);

Hi @enpu

Thanks for this! I've actually encountered this before, and completely forgot, that the graphics had to be created at (0, 0)

It works like it should now
