SprSetColor

[crazynate]

I am upgrading my avatar maker program and i was planning on adding better color options but i didn't want to make a lot of sprites. So i looked through sprite library guide, and i found the sprsetcolor function. At first i thought the format was
sprsetcolor(0-255,0-255,0-255) so i made a variable for each color
sprsetcolor(colors(0),colors(1),colors(2))

I ran the porgram and changed the value of the variables between 0-255. unfortunately it didnt work the way i had hoped & i only got a few colors. I reread the library guide and found out that 0 = no intensity, 1 = full intensity; so i changed the variables so that they would be 0-1
sprsetcolor(colors(0)/255,colors(1)/255,colors(2)/255)

But once again it didn't work. The red,the green, & the blue were either full intensity or not.
Can someone help me because i don't want to spend a lot of time making sprites and the last time i tried using opengl it crashed my computer's video card

Try using the true decimal values of the colors you want.

If you wanted a red color, it would be (200,37,54)

The way the SprSetColor function work is you use decimals like so

SprSetColor (0.3,0.8,0.5)

Now I don't know wat color that will be but is will work.

I've used it before and it's simple once u get ur head round the problem.

I've used decimals to 2 places but I think u can use them further.

I see what you are doing by deviding the values by 255 to get a decial, but because both numbers are integers the result will be trucated/rouded to an integer. the soloution I used is to declaire colors() as a double. Also instad of using an array you could use a UDT or Structure:
type spritecolor
red as double
green as double
blue as double
end type

dim ball as integer = NewSprite(LoadTex("data\ball.png"))
dim c as spritecolor
c.red = 255
c.green = 150
c.blue = 200

SprSetPos(100,100)
SprSetColor(c.red/255, c.green/255, c.blue/255)

Why make them floats?

Dim Red = 200, Green = 125, Blue = 20

SprSetColor (Red / 255.0, Green / 255.0, Blue / 255.0)

Just devide it by a decimal instead.
