A base class to implement to draw custom editors for custom VolumeParameter. You must use a VolumeParameterDrawerAttribute to let the editor know which parameter this drawer is for.

Syntax

public abstract class VolumeParameterDrawer

Remarks

If you do not provide a custom editor for a VolumeParameter, Unity uses the buil-in property drawers to draw the property as-is.

Examples

Here's an example about how ClampedFloatParameter is implemented:

[VolumeParameterDrawer(typeof(ClampedFloatParameter))]
class ClampedFloatParameterDrawer : VolumeParameterDrawer
{
    public override bool OnGUI(SerializedDataParameter parameter, GUIContent title)
    {
        var value = parameter.value;

        if (value.propertyType != SerializedPropertyType.Float)
            return false;

        var o = parameter.GetObjectRef<ClampedFloatParameter>();
        EditorGUILayout.Slider(value, o.min, o.max, title);
        value.floatValue = Mathf.Clamp(value.floatValue, o.min, o.max);
        return true;
    }
}

Methods

IsAutoProperty()

Override this and return false if you want to customize the position of the override checkbox. If you don't, Unity automatically draws the checkbox and puts the property content in a horizontal scope.

Declaration

public virtual bool IsAutoProperty()

Returns

Type	Description
Boolean	false if the override checkbox position is customized, true otherwise

OnGUI(SerializedDataParameter, GUIContent)

Draws the parameter in the editor. If the input parameter is invalid you should return false so that Unity displays the default editor for this parameter.

Declaration

public abstract bool OnGUI(SerializedDataParameter parameter, GUIContent title)

Parameters

Type	Name	Description
SerializedDataParameter	parameter	The parameter to draw.
GUIContent	title	The label and tooltip of the parameter.

Returns

Type	Description
Boolean	true if the input parameter is valid, false otherwise in which case Unity will revert to the default editor for this parameter
