Digging voxels
Result
How to
- Add a Position parameter to Game/EasySurvivalRPG/Blueprints/Interfaces/BPI_DiggingActor (note: this might not be needed in future ESRPG releases)
- In Game/EasySurvivalRPG/Blueprints/Characters/Base/BP_Character_Player, in the Complete Digging Server function, add the following (note: this might not be needed in future ESRPG releases)
- Make sure you have the plugin installed: https://free.voxelplugin.com
- Add a new voxel world to your scene
- Add a blueprint to that voxel world
- In the BP class settings add the BPI_DiggingActor interface
- Implement the Try to dig function in 4.26, just double click the function
- Add the following node. Make sure the radius is set to 50 (that's for a voxel size of 20 - for a larger voxel size, you'll want a larger radius)
- Go back to your level. If the voxel world is invisible, try clicking the Toggle button in the voxel world details panel.
- Set the Voxel Size to 20, the generator Color to orange and the Voxel Material to M_VoxelMaterial_Colors
- Go to your voxel world blueprint and do the same. Set the Voxel Size to 20, the generator Color to orange and the Voxel Material to M_VoxelMaterial_Colors
