# RealWorld
Pocketmine Generator for Earth and heightmap based generation.
# Installation
To support all the features including your own heightmap creation, you may need to install the PHP GD extension.
How to do that?
- For PocketMine Server Manager users, check if the plugin is working, if not, just delete the folder located in <YOUR\_OWN\_FOLDER>/.pocketmine/php and restart PocketMine Server Manager.
- For regular pocketmine user, you can get <a href="https://psm.mcpe.fun/download/PHP/compile.sh">the following script to install a PHP with GD included </a>.
You may also need to install https://sourceforge.net/projects/libpng/.
