Hello everyone,

I'm trying to create a script for brush opacity, hue, flow and other stuff because I want to put those on a dial..

here my script but I get the error 21: undefined is not an object line 5: if (activeTool.kind == ToolKind.BRUSH) {

Anyone can help? Thanks

// Get the active brush tool

var activeTool = app.activeTool;

// Check if the active tool is a brush tool

if (activeTool.kind == ToolKind.BRUSH) {

// Get the current opacity of the active brush

var currentOpacity = activeTool.settings.opacity;

// Calculate the new opacity

var newOpacity = currentOpacity - (currentOpacity * 0.05);

// Set the new opacity of the active brush

activeTool.settings.opacity = newOpacity; } else { alert("Please select a brush tool"); }

This should serve as an example of how to get information about the current Tool.

The screenshot shows the second alert for the Brush Tool for example:

if (app.documents.length > 0) {
var ref = new ActionReference();
ref.putEnumerated( charIDToTypeID("capp"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 
var appDesc = executeActionGet(ref);
//checkDesc2(appDesc);
alert (typeIDToStringID(executeActionGet(ref).getEnumerationType(stringIDToTypeID('tool'))));
var toolOptions = appDesc.getObjectValue(stringIDToTypeID('currentToolOptions'));
checkDesc2(toolOptions);
};
//////

function checkDesc (theDesc) {
var c = theDesc.count;
var str = '';
for(var i=0;i<c;i++){ //enumerate descriptor's keys
	str = str + 'Key '+i+' = '+typeIDToStringID(theDesc.getKey(i))+': '+theDesc.getType(theDesc.getKey(i))+'\n';
	};
alert("desc\n\n"+str);
};

Thanks so much for the reply! I'll give it a try for sure

Do you have any Scripting experience?

Are you familiar with UXP?

What kind of Dialog or Panel do you want to create (please post a sketch)?

By the way: ESTK Scripts can create modal dialogs (though there are supposedly work-arounds), if you want a non-modal Panel you would need to create a UXP Panel.

Which would probably be better anyway in the long run as ESTK Scripting appears to be on the way out.
