Makecode program crashes when rotating an image Moderators: adafruit_support_bill, adafruit

Dear PyGamer users

Rotating any image by 90 or 270 degrees let the MakeCode arcade game crash on the PyGamer. This very simple MakeCode arcade program crashes with the error code 821 when executed on the PyGamer (while it successfully runs in the simulator):

Code: Select all | TOGGLE FULL SIZE

img`1`.rotated(90);

I'm not sure if this is an issue with MakeCode arcade or with the PyGamer. Any clues where to do a proper error report?

Actually the call to image.transpose fails: img`1`.transpose()

As a workaround, use these functions here:

Code: Select all | TOGGLE FULL SIZE

function transpose(img: Image): Image {
    const result = image.create(img.height, img.width);
    for(let x = 0; x < img.width; x++) {
        for (let y = 0; y < img.height; y++) {
            result.setPixel(y, x, img.getPixel(x, y));
        }
    }
    return result;
}

function rotate(img: Image, deg: number): Image {
    if (deg == -90 || deg == 270) {
        const r = transpose(img);
        r.flipY();
        return r;
    } else if (deg == 180 || deg == -180) {
        const r = i.clone();
        r.flipX();
        r.flipY();
        return r;
    } else if (deg == 90) {
        const r = transpose(i);
        r.flipX();
        return r;
    } else {
        return i;
    }
}

Interesting. Could you share the original code you were using that was crashing?

Hi John

This super simple program crashes on my PyGamer with code 821:
