How to have a randomly changing colour background?

Ed_Perkin

Just to change colours randomly bu gradually , tried interpolating every 2 seconds to random green random(1,255) etc but won't work and just goes white , any suggestions?

You need to set your random number to generate between 0 and 1.

Random (0,1) will give you just 8 colours (out of a possible 16,777,216).

You can access all 167,77,216 colours with random(0,255)/255.

@Socks, even better!

Interpolate Red to random(0,255)/255

Interpolate Blue to random(0,255)/255

Interpolate Green to random(0,255)/255

This will give you the full 24bit range, but you might want to clip the lower and upper extents to avoid pure black or pure white . . . something like this . . . .

Interpolate Red to random(40,255)/255

Interpolate Blue to random(0,200)/255

Interpolate Green to random(40,255)/255

Alternatively you could have the colours slowly cycle through the spectrum (so you don't get any dull colours or pure black or white . . .

Constrain Red to 0.5 *sin( game.Time *50)+0.5

Constrain Green to 0.5 *sin(( game.Time *50)+120)+0.5

Constrain Blue to 0.5 *sin(( game.Time *50)+240)+0.5

An even brighter spectrum with the top and bottom of each channel clipped . . . .

Constrain Red to sin( game.Time *50)+0.5

Constrain Green to sin(( game.Time *50)+120)+0.5

Constrain Blue to sin(( game.Time *50)+240)+0.5

Thanks @socks This is gonna help! Might use this one or the next one aha :
"Interpolate Red to random(0,255)/255
Interpolate Blue to random(0,255)/255
Interpolate Green to random(0,255)/255"
