Hello, everyone! I’m working on implementing a dynamic brush preview feature in the WorldEdit plugin for Bukkit. Here’s the feature I’m trying to achieve: When a brush is activated, the plugin should show a preview (using placeholder blocks like glass) of the brush’s effect at the player’s target location. The preview should dynamically update as the player moves or looks at different locations. When the brush is applied, the actual blocks are placed, and the preview should clear. The preview must respect the world’s state, meaning it doesn’t overwrite or permanently affect blocks until the brush is actually used. What I’ve Tried So Far: I’ve added a preview method to the Brush interface to generate the glass preview. I’m using PlayerMoveEvent to detect player movement and update the preview. I attempted to clear previous preview blocks, but I’m running into issues where the preview doesn’t clear or update correctly. I’ve also considered using a scheduler (BukkitRunnable) for periodic updates but haven’t gotten it working perfectly yet. My Current Problems: Preview blocks aren’t updating dynamically as the player looks around. Clearing previous previews without accidentally breaking blocks modified by other brushes. Ensuring performance remains smooth, especially with larger brushes. Code Snippets: (I’d include the key methods for the preview and clear logic here, e.g., renderPreview, clearPreview, etc., along with details about the context.) I’d greatly appreciate any advice, suggestions, or code samples to help refine this feature. If anyone has experience integrating dynamic previews or handling similar use cases in WorldEdit or Bukkit, your insights would be invaluable!
