Apologies for the delay. A color is just a number in GameMaker, so you should just be able to use gms_self_set and gms_other_get to sync the variable (for player variables), or gms_instance_sync_var_add/gms_instance_set/gms_instance_get (for instance syncing). Could you post the code that you're using to sync the variable?

here is the code:
BrickColor = global.BrickColor
gms_instance_sync(id,is_extended)
gms_instance_sync_var_add("BC",BrickColor)

All calls to gms_instance_sync_var_add must appear before the call to gms_instance_sync. Swapping those two calls should make your code work. (assuming you also have the corresponding code in the user defined event to load the value again)

i did that but still dosen't sync here is a screenshot:https://i.ibb.co/HdY8WY1/RBLX2-D-screenshot-brickcolor-missing.png

Could you show the code you're using in the user defined event 12 of the brick?

wasn't it 15? because thats the only one i use and i just looked up and has nothing on it

You will need to load the variable in the User Defined 12 event. For example, something like this:

mycolor = ds_map_find_value(variable_map, "BC");

variable_map is a variable that contains a ds_map with all the variables you added using gms_instance_sync_var_add. Obviously you then need to somehow use 'mycolor' to actually draw the right color in, for example, the draw event.

also i forgot to mention something idk if it is the cause of the problem but the global.brickcolor is a make_colour_rgb value

make_colour_rgb just returns a number, that's fine. If you have the gms_instance_sync_var_add and the code to load the value in the User Defined 12 event it should work.
