The OnUpdate method is a virtual method in the BaseBrushTool class, which is part of the Editor.TerrainEditor namespace. This method is intended to be overridden by derived classes to implement custom update logic for terrain brush tools. It is called every frame to update the state of the brush tool.
To use the OnUpdate method, create a class that derives from BaseBrushTool and override the OnUpdate method. Implement the desired behavior that should occur every frame while the brush tool is active. This could include updating the brush position, handling user input, or modifying terrain data.
public class CustomBrushTool : BaseBrushTool
{
public override void OnUpdate()
{
// Custom update logic for the brush tool
// For example, update the brush position based on user input
Vector3 brushPosition = GetBrushPosition();
ApplyBrush(brushPosition);
}
private Vector3 GetBrushPosition()
{
// Logic to determine the brush position
return new Vector3(); // Placeholder
}
private void ApplyBrush(Vector3 position)
{
// Logic to apply the brush effect at the given position
}
}
