Okay, I have begun working on a function that will take an area of the screen and blend it equally with a color as a parameter.

The code I currently have (in code attatchment), doesn't function at all. I am under the understanding that Lock Pixels can do better than point and dot, however I have no idea how it works or what it is supposed to do!

I tried at first to take the dword color data and get the average between that and the color parameter but that gave me some very funky results (looked like a weird tie die pattern). Then I tried averaging each color, however that causes my program to crash on running. I can't even hit the escape key!

Thanks in advance

EDIT -- Okay I did fix one problem in that I spaced out those several if statements over a few lines. Forgot that if I put a semicolon it would add to the stuff done in that if block. However it hasn't helped. I am DBPro FYI

IF R3 > 255 THEN R3 = 255: IF G3 > 255 THEN G3 = 255: IF B3 > 255 THEN B3 = 255
IF R3 < 0 THEN R3 = 0: IF G3 > 0 THEN G3 = 0: IF B3 > 0 THEN B3 = 0

Try it with colons which should properly separate commands.

unfortunately you haven't found out yet that dbpro doesn't like if-then statements on the same line. it just doesnt! caused me many hours of frustration! my advice would be to simply put them all on their own line or make them if-endif.

*or maybe my comp is just messed up...*

Okay I am posting this to help people avoid wasting there time. Unfortunately noone read my edit post so they wasted there time.

All the IF THEN Statements are now on separate lines. It still doesn't work.

Sorry if that sounded rude but would rather save space for things that are relevant.

Thanks for your time, however.

Hi Black Hydra II,

yeah you've used the variable "B" twice. Once for the FOR/NEXT loop and once for the blue colour component. Change the one for the loop and it should work fine.

And yeah simply add LOCK PIXELS before your FOR/NEXT loops and UNLOCK PIXELS after them for a speed boost.

Thanks Fog.

I was almost positive I was doing something wrong with using the color commands. (My first time using them) I should have looked for the more obvious culprits more strenously.
