Hey Chris, how are you ?
Yes, it is possible. The csv has the following pattern:
, en, pt_BR
ID1, text, texto
ID2, color, cor
To import/export the translation file, click on the Gear Icon and select the Translation Section.
To use the translation you must use %ID1%
for example
My example code that i use in my game:
display_message("%ID10% " + str($choiceToItemName[$choice]) + "!");
