Actual gamma correction takes every pixel on the screen and raises its R,G and B components by a power of 1/gamma, assuming that the values of RGB are between 0 and 1. The game's implementation just makes the whole screen brighter, but things are still hard to see because the contrast is low.

This mod changes the UpdateScreenGamma function to be closer to what gamma correction actually is.

Drag this into your SCP-CB (v1.0.6) folder and run it.

Source code changes:
Main.bb
Replace UpdateScreenGamma with this:

Code: Select all

Function UpdateScreenGamma()
	Local n# = 1.0/ScreenGamma
	Local k%
	
	For k=0 To 255 
		Local c# = Min(Max(0, ((k/255.0)^n)*255), 255)
		SetGamma k,k,k,c,c,c
	Next 
	UpdateGamma 
End Function

Menu.bb
Replace line 486 with this:

Code: Select all

ScreenGamma = (SlideBar(x + 310*MenuScale, y+6*MenuScale, 150*MenuScale, ScreenGamma*50.0)/50.0)

Very nice! Has to be a part of the game itself tbh. This would be called a, "contrast," setting but, whateva. :p

Awesome! I thought something seemed a little off about it.

Actualy, yes. I agree with Abincyprus, it is more of a "Contrast" setting, but Fine job.

Thank you so much for this!

Though sadly it doesn't work if recording the screen :c

this question might be stupid but if you make the gamma level high, will it emit the gamma radiation?

What kind of question is this? Does your PC explode if you play a video of a nuke?
