hello,

i'm new to the SDK, when setting the background colour i need to pass one int the color, what are the values to be given for white,

the r,g,b are not passed so what determines what colour is what value, e.g. black is lower, white higher etc?

cheers

In the DarkSDKBasic2D.h file, there's a function called dbRgb()

Use this to convert an r, g, b value into the int you need

Its a 32-bit colour (the top 8 are ignored), thus :

xxxxxxxbbbbbbbbggggggggrrrrrrrr

it could be the other way around (rgb).

Anyway, the intensity of these 8 bits define the colour - hence by RGB values are passed, and not usually just any old integer. Higher values produce a lighter colour.

Thanks guys that worked great.

On another issue, i have used dbLockObjectOn on some plains to create some icons for my program, however the pick object command does not seem to work on these objects. It is working on objects in the scene so must be because they have been locked to screen, any reason for this?


My FPS also stay around 60 even with just 1 rotating cube on screen. Sync rate is set to 100 so it isnt the cap of sync rate, my graphics card normally produces higher on dbpro, is this common?

As far as I know, locked objects cannot be picked. The reason is the way the engine handles these objects.
However you can use some manual locking, there are some snippets for this at the code snippet forum.

About the FPS question, you may know that this is an already published bug for 1.6.2c
It shows always 60, because that is the refresh rate of your monitor. So setting sync rate is kind of useless.

[Edit] I suggest you to start a different thread for each different question.
