Hey guys!

Im trying a new version of my game that its basicly everything custom.
You can make your own mods and stuff.

So i want to people put the background color with the RGB: 0, 255, 5
It is bright green and now i made a sprite with that color and the color is still there..

What's happening?

PS: The dbSetImageColorKey(0,255,5); is inside the loop and in void darkgdk startup

dbSetObjectTransparency
This command will set the transparency state of the specified object. Setting the transparency to one will ensure the object does not draw the transparent colour during final rendering. The transparent colour is determined by the dbSetImageColorKey command.

Syntax
void dbSetObjectTransparency ( int iObject, int iFlag )

dbSetImageColorKey() must be called before loading your image too.

PNG ? - It might be assuming you want alpha channel from the image format.


Hmm, I wonder what's coming in 2011?

Yes, if you saved it as PNG then that's the problem. Color key works correctly with BMP.

There is also a command to switch sprite transparency on and off:



but the default flag settings are 1,1 so it should work without this command, if you save the sprites in BMP format.

You have two choices:

1. Save the image in BMP format and use the colour key command. For this, even Windows Paint is enough, it can load PNG and save BMP.

2. Save the image in PNG format, but with transparency, and then you don't need the colour key. For this you need an image editor that can handle transparency. For example in Paint Shop Pro, when you export into PNG, you can select which will be the transparent colour and then transparency is saved into the file.

You can also check if the program that the original file was made with (I don't know what "idi" is) can export into a different format.

well

i use paint.net that has transparency

but as i want players to make their graphics and i want it dynamic that allow players to make with all editors i want to use colour key but the problem is that BMP takes some space..

.idi its: Island Defender Image (a extension created for the game) that just changes in the name.
