I have made a splitting string ("c_red|c_black|c_blue").
The split array script will split it into 3 arrays...
But the problem is that the values are strings and not colors...
how can I convert them into color constants? (the real from string doesn't work)

Many thanks.

Not 100% sure of your question, but i think you're probably looking for make_color_rgb() or make_color_hsv()

make_color functions create color database depending on 3 colors (red,blue,green) and then create another combined color.
Game maker has precombined colors like c_red for example that already has the rgb combination.
I have a string precombined color "c_red" and I want the system to recognize it and use it as a regular c_red.

This question can be applied to a lot of constant types, like sprites, sounds and objects.
meaning, you have a sprite name in a string and you want it to be recognized as a image name.

found a way, use this code:
string_execute("return "+color_string);

string_execute("return "+color_string);

THANKS MAN<!
Worked wonderfully, I never thought about using execute_string.

And yeah, its execute_string and not string_execute...
I used it like this: execute_string("return "+color[0]);

Many thanks.

[Reopening Topic]
is there a way to do this without using "string_execute"?
because that particular function was scrapped for being "obsolete" in Game Maker Studio+

make a ds_map and add all your constants in it

colors = ds_map_create();
//fill with string and actual values
ds_map_add(colors,"c_white",c_white);
ds_map_add(colors,"c_red",c_red);
...

to get the color

ds_map_find_value(colors,"c_white")

[jo-thijs]

I guess it would be better then to use:
if strcolor=="c_white"
rlcolor=c_white;else
if strcolor=="c_black"
rlcolor=c_black;else
...

ds_map_find_value(colors,"c_white")

I think its a good way to do it, although I never used ds_map functions.
I'll give it a try, many thanks.

rlcolor=c_white;else
if strcolor=="c_black"
rlcolor=c_black;else

Its a good way to go also, It does give a quicker solution, it is probably better than creating an entire database of colors like the ds_map.

Both of the ways are suitable and ill try them both, many thanks.

you can also make a huge case statement.
