KhaledFelfal There is a thousand different reasons why this can happen. See Ashley's comment - press F12 and look for error messages in the console log.

Thanks, Ashley and chadorireborn !

So will the splash image be scaled on different screens, or placed as it it? For example, if the project viewport is 1080x1920 and the splash image is 1000x1000, will it be scaled down or cropped on smaller screens?

I agree with dupuqub - MoveTo has "Add waypoint" mode, it's the easiest solution. Check out this demo, basically event #4 is all you need.

Your first link doesn't work. You need to allow access to the file for everyone. (Try opening this link in another browser or in Private Mode, to check if it's working)

If you have multiple DrawingCanvas instances, you either need to process them one by one, or add many empty frames into the TempSprite and load each image into a separate frame.

Drawing Canvas doesn't like scaling. You need to move the image to a temporary sprite, then change the size of canvas, then paste the sprite back.

Try this:

Each pixel uses 4 bytes in the imageData array (r, g, b, a). So here is how to get pixel data at row:x, column:y

function getColorAtPixel(imageData, x, y) {
 const {width, data} = imageData

 return {
 r: data[4 * (width * y + x) + 0],
 g: data[4 * (width * y + x) + 1],
 b: data[4 * (width * y + x) + 2],
 a: data[4 * (width * y + x) + 3]
 }
}

Ashley , could you please explain how the color is encoded in the ColorValue? I.e. is there a way to extract r/g/b/alpha channels from it? I couldn't find this info anywhere.

Ok, you can use any other event instead of "On collision" - for example "On Key Pressed" or "On Touch".
On (whatever event you use to fire a bullet) Platform is visible -> Platform Set invisibile Else -> Platform Set visibile

So what's the problem? Have you tried the code I posted in my first comment?

Bullet on collision with Platform -> If Platform is visible - set invisible, Else set visible.
