# Add UI for Brush controls
|
|
|
|
[Create your tool script](create-tool-script.md) showed you how to create a new custom tool without any additional functionality. The example below shows you how to add UI for Brush controls in your script.
|
|
|
|
```
|
|
using UnityEngine;
|
|
using UnityEditor;
|
|
using UnityEditor.TerrainTools;
|
|
|
|
internal class CustomTerrainToolWithBrushUI : TerrainPaintTool<CustomTerrainToolWithBrushUI>
|
|
{
|
|
private float m_BrushRotation;
|
|
|
|
// Name of the Terrain Tool. This appears in the tool UI.
|
|
public override string GetName()
|
|
{
|
|
return "Examples/Custom Terrain Tool with Brush UI";
|
|
}
|
|
|
|
// Description for the Terrain Tool. This appears in the tool UI.
|
|
public override string GetDesc()
|
|
{
|
|
return "This is a very basic Terrain Tool that doesn't do anything aside from appear in the list of Paint Terrain tools.";
|
|
}
|
|
|
|
public override void OnInspectorGUI(Terrain terrain, IOnInspectorGUI editContext)
|
|
{
|
|
editContext.ShowBrushesGUI(5, BrushGUIEditFlags.Select | BrushGUIEditFlags.Opacity | BrushGUIEditFlags.Size);
|
|
m_BrushRotation = EditorGUILayout.Slider("Rotation", m_BrushRotation, 0, 360);
|
|
}
|
|
|
|
public override void OnRenderBrushPreview(Terrain terrain, IOnSceneGUI editContext)
|
|
{
|
|
|
|
}
|
|
|
|
public override bool OnPaint(Terrain terrain, IOnPaint editContext)
|
|
{
|
|
return true;
|
|
}
|
|
}
|
|
```
|
|
|
|
This example still doesn't do much, but it does give some useful information about the Brush.
