Metropolis Like Boss

by Tpot, quoted from the SFGHQ discord server.

Made this as a proof of concept for something. It's basically the Metropolis Zone boss animation in a couple lines of code. While it's in GML, it's so short, you can easily convert the logic. https://i.gyazo.com/79fde74271b9a2020745377d6cf3171b.mp4 Create:

    nodeObj   = objNode;

    xRadius   = 96;

    yRadius   = 96;

    angle     = 0;

    aSpeed    = 2;

    nodeCount = 16;

    for(i=0;i<nodeCount;i+=1)

        nodes[i] = instance_create(x,y,nodeObj);

Update/Step

    angle += aSpeed;

    for(i=0;i<nodeCount;i+=1){

        _r  = i*(360/nodeCount)+angle;

        deg = degtorad(_r);

        _c  = cos(deg);

        _s  = sin(deg);

        nodes[i].x = x+xRadius*_c;

        nodes[i].y = y+yRadius*_s;

0:07/0:07

The code shown here also has

    xRadius += keyboard_check(vk_up)    - keyboard_check(vk_down);

    yRadius += keyboard_check(vk_right) - keyboard_check(vk_left);

To control the shape.

Though depth is not taken into account, only because GM8 acts oddly when you change an objects depths every frame.
