How do I get RGB values from a colorvalue?

Is there a reverse function for the following expressions?

rgbEx(r, g, b)

rgbEx255(r, g, b)

rgba(r, g, b, a)

rgba255(r, g, b, a)

You would have to paste into a Drawing Canvas and get the pixel color SnapshotRedAt(x, y) SnapshotGreenAt(x, y) SnapshotBlueAt(x, y)

Takes a tick, or two.

That's unfortunately clunky. Guess manually setting three variables when using colorvalue to set color is the cleanest way for now.

R0J0hound Is this for rgb expression in C2? I don't think this works in Construct 3.

A method I find useful. I like to work with palettes but the rgb expressions don't work well for that, so instead I use the formula R+(G*256)+(B*65536) to store my color data in an array, then just pop the index into the set color.

Ah. Well looking at the values further it looks like there are 10bits per component instead of 8. They didn’t end up being spaced out every 10 bits but I came up with this.

Basically if the color is negative you can get the colors back with this. Internally each component can have 1024 values.

If the color is positive then my previous answer should apply. But only the old rgb() expression should do that.

R=int(-color/2^38)%1024*255/1023

G=int(-color/2^26)%1024*255/1023 B=int(-color/2^10)%1024*255/1023 A=(-color)%1024*255/1023

It doesn’t give the exact value but it should be spot on if you round it. Unless I made a mistake somewhere.

Awesome, thanks!

Probably replace 1024 with 1025 but I haven’t tested it.

Yes - works perfectly. Thank you.
