Same Action to multiple HUD elements – ShiVa Engine

Same Action to multiple HUD elements

Code your action by hand, not with the HUD editor. If you give your components generic names with a number at the end, you can write a simple for-loop that will assign the action to every component with the correct component name.
For this sample to work, i assume your main menu buttons are named MainMenuButton_0 to MainMenuButton_30.

    --initialze HUD
    hud.newTemplateInstance ( application.getCurrentUser ( ), "YourHudName", "MMenu" )
    local hUser = application.getCurrentUser ( )
    for i=0, 30, 1 do
        --create scaleup action
        local hActionScaleUp = hud.newAction ( hUser, "ScaleUpMMButton_"..i )
        hud.beginActionCommand ( hActionScaleUp, hud.kCommandTypeInterpolateSize )
        hud.pushActionCommandArgument ( hActionScaleUp, hud.getComponent ( hUser, "MMenu.MainMenuButton_"..i ) )
        --set your own scaling values here
        hud.pushActionCommandArgument ( hActionScaleUp, 10 )
        hud.pushActionCommandArgument ( hActionScaleUp, 10 )
        hud.pushActionCommandArgument ( hActionScaleUp, hud.kInterpolatorTypeLinear )
        hud.pushActionCommandArgument ( hActionScaleUp, 50 )
        hud.endActionCommand ( hActionScaleUp )
        --create scaledown action
        local hActionScaleDown = hud.newAction ( hUser, "ScaleDownMMButton_"..i )
        hud.beginActionCommand ( hActionScaleDown, hud.kCommandTypeInterpolateSize )
        hud.pushActionCommandArgument ( hActionScaleDown, hud.getComponent ( hUser, "MMenu.MainMenuButton_"..i ) )
        --set your own scaling values here
        hud.pushActionCommandArgument ( hActionScaleDown, 6 )
        hud.pushActionCommandArgument ( hActionScaleDown, 6 )
        hud.pushActionCommandArgument ( hActionScaleDown, hud.kInterpolatorTypeLinear )
        hud.pushActionCommandArgument ( hActionScaleDown, 50 )
        hud.endActionCommand ( hActionScaleDown )
        --get button
        local hComponent = hud.getComponent ( hUser, "MMenu.MainMenuButton_"..i )
        if hComponent then
            hud.addComponentEventHandler ( hComponent, hud.kEventTypeMouseEnter, hud.getAction ( hUser, "ScaleUpMMButton_"..i  ) )
            hud.addComponentEventHandler ( hComponent, hud.kEventTypeMouseLeave, hud.getAction ( hUser, "ScaleDownMMButton_"..i  ) )
            log.message ( "new mouse handlers for button "..i.." added!" )
        end
    end
