Description

Base class for terrain painting tools.

Derive from this class to implement your own terrain painting tools.

using UnityEngine;
using UnityEditor;
using UnityEngine.Experimental.TerrainAPI;

namespace UnityEditor.Experimental.TerrainAPI { public class MyPaintHeightTool : TerrainPaintTool<MyPaintHeightTool> { Material m_Material = null; Material GetPaintMaterial() { if (m_Material == null) m_Material = new Material(Shader.Find("Hidden/Terrain/PaintHeight")); return m_Material; }

public override string GetName() { return "My Paint Height Tool"; }

public override string GetDesc() { return "Left click to raise.\n\nHold shift and left click to lower."; }

public override void OnSceneGUI(Terrain terrain, IOnSceneGUI editContext) { TerrainPaintUtilityEditor.ShowDefaultPreviewBrush(terrain, editContext.brushTexture, editContext.brushSize); }

public override bool OnPaint(Terrain terrain, IOnPaint editContext) { Material mat = TerrainPaintUtility.GetBuiltinPaintMaterial();

float rotationDegrees = 0.0f; BrushTransform brushXform = TerrainPaintUtility.CalculateBrushTransform(terrain, editContext.uv, editContext.brushSize, rotationDegrees); PaintContext paintContext = TerrainPaintUtility.BeginPaintHeightmap(terrain, brushXform.GetBrushXYBounds());

// apply brush Vector4 brushParams = new Vector4(editContext.brushStrength * 0.01f, 0.0f, 0.0f, 0.0f); mat.SetTexture("_BrushTex", editContext.brushTexture); mat.SetVector("_BrushParams", brushParams); TerrainPaintUtility.SetupTerrainToolMaterialProperties(paintContext, brushXform, mat);

Graphics.Blit(paintContext.sourceRenderTexture, paintContext.destinationRenderTexture, mat, (int)TerrainPaintUtility.BuiltinPaintMaterialPasses.RaiseLowerHeight);

TerrainPaintUtility.EndPaintHeightmap(paintContext, "Terrain Paint - MyPaintHeightTool"); return false; } } }
