Polypaint toggle button

ZScripting Help
#1

This works for the first 8 subtools in the list (as long as I haven’t scrolled down). It doesn’t work on any other subtool. Why? I believe it has something to do with SubToolGetActiveIndex.

I’m stumped. Thanks.

//Create button[IButton,"PolyPnt Sel","Toggle PolyPaint On/Off for ACTIVE subtool",
[IFreeze,
    [IShowActions,0]
//Create variable for polypaint state (On or Off?)
    [VarDef,ppStateSel,0]    
    
//Create variable to store currently selected subtool
    [VarSet,activeSubT,[SubToolGetActiveIndex]]


//Put polypaint state/value into variable
    [VarSet,ppStateSel,[IModGet,[StrMerge,"Tool:Subtool:Subtool ",#activeSubT]]]


//If on, turn off ... If off, turn on
    [If,ppStateSel = 25, //Vis On,PP On
            [IUnPress,Tool:Polypaint:Colorize] //turn PP off
    ]
                    
    [If,ppStateSel = 17, //Vis On,PP Off
            [IPress,Tool:Polypaint:Colorize] //turn PP On
    ]
        
    [If,ppStateSel = 9, //Vis Off,PP On
            [IUnPress,Tool:Polypaint:Colorize] //turn PP Off
    ]
                
    [If,ppStateSel = 1,  //Vis Off,PP Off
            [IPress,Tool:Polypaint:Colorize]
    ]

You can’t use the active index like that. The reason is that it will give you the subtool index in the list from 0 to (total number of subtools minus 1), whereas the number in the path to the selected subtool will only be from 0 - 7.

You can use the name of the subtool instead, like this (though note that you might get unexpected results if there are duplicate subtool names):


    [VarSet,activeSubT,[SubToolGetActiveIndex]]
    //this makes sure there is no error if the active subtool is hidden
    [If,([Val,activeSubT+1] == [SubToolGetCount] ),
      [SubToolSelect,0]
      ,
      [SubToolSelect,[Val,activeSubT+1]]
    ]   
    [SubToolSelect,activeSubT]
    [VarSet,subToolPath,[IGetTitle,Tool:Item Info]]//get subtool name
    [VarSet,subToolPath,[StrExtract,subToolPath,0,[StrLength,subToolPath]-2]]//trim off period
    [VarSet,ppStateSel,[IModGet,[StrMerge,"Tool:Sub Tool:",subToolPath]]]

    //If on, turn off ... If off, turn on
    [If,ppStateSel = 25, //Vis On,PP On
            [IUnPress,Tool:Polypaint:Colorize] //turn PP off
    ]
                    
    [If,ppStateSel = 17, //Vis On,PP Off
            [IPress,Tool:Polypaint:Colorize] //turn PP On
    ]
        
    [If,ppStateSel = 9, //Vis Off,PP On
            [IUnPress,Tool:Polypaint:Colorize] //turn PP Off
    ]
                
    [If,ppStateSel = 1,  //Vis Off,PP Off
            [IPress,Tool:Polypaint:Colorize]
    ]

The first bit of code is necessary to make sure the active subtool is visible in the subtool list. If the subtool is hidden you will get an error when trying to use IModGet saying the item ‘does not have special modifiers’.
