How do I make color wheel or color picker ?

I want to make a color wheel from where I can pick color and then adjust gradient.

Any tip ?

First paste a color wheel onto a drawing canvas object. Then use the save snapshot action. Afterwards you can use the snapshot(rgba)at(x,y) expressions to get the color from any given pixel in number form, and do whatever you want with it.

construct.net/en/make-games/manuals/construct-3/plugin-reference/drawing-canvas

SnapshotRedAt(x, y)

SnapshotGreenAt(x, y)

SnapshotBlueAt(x, y)

SnapshotAlphaAt(x, y)

Return the red, green, blue and alpha components of a pixel in a saved snapshot. The position is given in pixel co-ordinates, and the returned value is returned in the 0-100 range. For more information see the section Pixel manipulation with snapshots above.

Thanks for the tip
