Hi, i have two sliders and i need that only when the user is moving them a functions is calling.
I need to check when a specific slider is changing (for example with a bool like sliderOneisChanging set to true during the movement) and call a function during the value modification,
here’s the code of the slider:

void OnGUI () {
	GUI.contentColor = Color.black;
	float width = GUILayout.HorizontalSlider(myVarWidth, 100f, 600f);
	float height = GUILayout.HorizontalSlider(myVarHeight, 100f, 600f);

}

Thank in advance for help

You can do it this way:

void OnGUI () {
    GUI.contentColor = Color.black;
    float width = GUILayout.HorizontalSlider(myVarWidth, 100f, 600f);
    if (width != myVarWidth) {
        // Set a bool or call a funciton
        myVarWidth = width;
    }

    float height = GUILayout.HorizontalSlider(myVarHeight, 100f, 600f);
    if (height != myVarHeight {
        // Set bool or call a function
        myVarHeight = height;
    }
}
