If you have a moment

First version of my HSV-utilising, pseudo-pallete-shifting, I-can't-be-bothered-to-draw-more-sprites colour functions.

system.vc has two autoexec loops, the currently uncommented out runs a pretty display once, near the top of the file are some variables you can change. The other one takes input and modifys some coloured squares as a test. Arrow keys and enter.

I've nicked a few avatars and stuff a bundled them in the directory, hope no one minds. Saves you finding your own images.

Not done any kind of optimizations yet, bar removing a few pointless variables, so some kind of speed feedback would be nice too.

Around 12 seconds. Seems reasonable, considering my slow system.

Good work.

Give the new version a go


Glad speed isn't too much of an issue, can never tell on this beast. The previous autoexecs are still in the system.vc, but this new one is pretty nice.
I'm beginning to suspect that I might not be allowed to do what I am currently for the colour swapping, but it does kinda work so I'm loath to change it.

ss_pixel = GetPixel(x, y, ss_image);


if (ss_pixel != COLOUR_MAGENTA) {


RGBtoHSV(GetR(ss_pixel), GetG(ss_pixel), GetB(ss_pixel));


ss_pixel = (ref_h - ss_col_out) % (360 - PLAY);


if (ss_pixel  (0 - PLAY)) // If this pixel matches the old colour


	// Set the pixel to the new shade


	SetPixel(x, y, HSVtoC((360+ss_col_in+ss_pixel)%360, ref_s, ref_v), ss_image); }

Think the % (360 -PLAY) does get if the hue is in range, but doesn't return the right value for modifying with later. Anyway...
