Parkour Rooms Template

Have you ever seen those "100 Rooms" Maps and wanted to make one of your own? Well, now you can! You can use this template however you want, and crediting me is optional for this. The rooms are all 12x20x12 big, with 10x19x10 on the inside to work with. Replacing the default block (Block of Quartz) can be done here: /fill ~20 ~7 ~20 ~-20 ~-7 ~-20 (example) replace quartz_block
