[Solved] imagebutton to pick different screens depending on variable

[daniople]

Hello! I'm currently stuck trying to figure out the correct syntax for what im trying to do. I have a screen with 4 imagebuttons, and I'm trying to get each imagebutton press to do the following:

• 1. to add + 1 to a variable: drink1_ingredients (this has been accomplished with SetVariable)

• 2. depending on the current value of the previous variable (drink1_ingredients), to display a screen with the corresponding number (either "milk1", "milk2", or "milk3".)

At the moment, clicking on the imagebutton once (the milk one for example) once has all 3 milks show up, regardless of the value of drink1_ingredients. i want to be able to add the 3 'milks' one click at a time.


here's what i have so far for the code of the imagebutton:

Code: Select all

    imagebutton:
        xpos 220
        ypos 250
        auto "images/UI/milk_%s.png"
        action [SetVariable("drink1_ingredients", drink1_ingredients + 1), If("drink1_ingredients = 1", Show("milk1")), If("drink1_ingredients = 2", Show("milk2")), If("drink1_ingredients = 3", Show("milk3"))]

and here is the traceback:

Code: Select all

I'm sorry, but an uncaught exception occurred.

Use == for comparison, without the quotes.

Code: Select all

action SetVariable("drink1_ingredients", drink1_ingredients + 1), If(drink1_ingredients == 1, Show("milk1")), If(drink1_ingredients == 2, Show("milk2")), If(drink1_ingredients == 3, Show("milk3"))
