Drag & Drop equivalent : 
str = a string (the question) that the user is supposed to answer yes or no to, it can be a string inside quotation marks, or it can be a variable without quotations.
This function will make a message box appear, but this message box will have 2 choices, yes and no, just like the corresponding drag & drop action. You must store this in a variable, otherwise your yes/no info will be discarded from the game.
Example #1:
//exit game code //escape press event quit = show_question("do you want to exit") switch(quit) { case 0: break; case 1: game_end();break; } // note that for this to work you must in the global game settings menu, // disable "let escape end the game" |
Example #2:
//in the space pressed event learn = show_question("do you want to learn gml?") if learn = false then { show_message("then exit this program") } else if learn = true then { show_message("then this is a good program to learn from") } |
