  • I'm creating buttons, and many of the effects and events are repeated many times.

    For example I have this condition:

    Main Condition

    Mouse->On Left Button Clicked on "Button"


    Touch-> Is Touching "Button"

    Sub Condition

    System -> Trigger once

    How Can I create in construct language something that receice a button as parameter, and check all of this conditions, to be used instead of repeating all of this?

  • Usual way is to create a function, pass it as a param the UID of a button object. In the function, pick the object from UID then do what you want.

  • This works fine for actions, but this doesn't work for conditions, I can't find a way to put a function call as a condition.


  • But on the function conditions there is only the "Compare Parameter" and the "On Function".

    Are you using another plugin to do this?

    You could put all of your different buttons into a family and assign an instance variable to the family, where you store the desired action.

    Then you check for mouseclicks like so:

    On left mouse button clicked on ButtonFamily -> call function CheckForButtonPress(ButtonFamily.UID)

    On Function "CheckForButtonPress"

    Pick ButtonFamily with UID function.param 0

    Compare ButtonFamily.Variable

    ButtonFamily.Variable = "menu" -> Call Menu

    ButtonFamily.Variable="quit" -> Quit


    I hope it's somewhat understandable.

    But it will not work with the free version of Construct 2, because of families.

  • that's about how I'd approach it, and I see luizfbicalho already has a license so that should be okay.

  • Compare ButtonFamily.Variable

    ButtonFamily.Variable = "menu" -> Call Menu

    ButtonFamily.Variable="quit" -> Quit


    ok I misunderstood the OP. Callbacks is a good solution but you can just do Function: Call ButtonFamily.Variable() as a shortcut.
