adding input combinations to a custom editor script?

Questions & Answers
1

Basically, I am trying to add in a ‘Ctrl + Scrollwheel’ input to change a variable up for a positive scroll or down for a negative scroll in an editor script that i am creating.

What is the best way to approach this input combination for the editor?

Everything i have looked up mostly refers to adding a Ctrl activation to a menu item and this is not what i am looking for.

~EDIT~

Upon further searching, i have stumbled upon code references that may be useful, but i can’t seem to get them to work to do what i need. There is a bool variable named ‘modifier’ declared with the other variables as well one called inc which i am using to try and limit the scroll wheel to only one call per scroll.

Event e = Event.current;

    if (e.isScrollWheel && e.control) {
        if (e.delta.y == 3 && inc)
        {
                Debug.Log(e.delta.y);
                selectedPrefabNum -= 1;
            inc = false;
        }
        else if (e.delta.y == -3 && inc)
        {
                Debug.Log(e.delta.y);
                selectedPrefabNum += 1;
            inc = false;
        }
    }

The Event class always hold the state of the 3 modifier keys: alt, control and shift.

So there’s no need to track the modifier state yourself. However if you do, you have to react to the KeyDown and KeyUp events

switch (e.type)
{
    case EventType.KeyDown:
        {
            if (Event.current.keyCode == KeyCode.LeftControl)
                modifier = true;
        }
        break;
    case EventType.KeyUp:
        {
            if (Event.current.keyCode == KeyCode.LeftControl)
                modifier = false;
        }
        break;
    // ...
