Player color alpha change. - Zh3r0 - 20.06.2011

How can i change just the Alpha channel of the color of the player?

For example, my color currently is 0x94ED40FF, how can I just change the transparency?

Something like

pawn Код:

GetPlayerColor(playerid) +/- 0x000000FF

or something? I know it sounds rubbish, but any ideas? ****** is good into this.

ANY_COLOR & 0x000000FF will return the alpha part only. This ranges from 0 (00) to 255 (FF)
So you could use this to set the alpha to whatever you like:

NEW_COL = ANY_COLOR - (ANY_COLOR & 0x000000FF) + new_alpha;

Where alpha should not be bigger than 255.
There might be more efficient methods, but this was the first one that came up in my mind.

Make a function that would change the last two characters which changes the transparency. I think that's it.

EDIT: Not sure if you want to make a command for it. But yeah, to change the transparency, change the last two characters.

I know what a HEX code is, I just need to change the Alpha channel via a function or a method, not human method, something that has to do with + and -.

@Mauzen, thanks, gotta try that!

Код:

NewColor=Color&0xffffff00+Alpha;

this is like the inversion of mauzens idea

Sorry and that's why I edited my post and asked.
