The Ultra Space plugin Allows you to restrict access to specific worlds and regions where players can only access them using a defined set. You can create oxygen tanks, necessary for the different worlds. These can be fully configured, defining how often oxygen will be taken.
PUNISHMENT MODES
There are several types of punishment for when you run out of oxygen or remove a part of your suit.
- DEATH
- INSTANT DEATH
- SPAWN
The plugin is compatible with Itemsadder; you can use its ID to directly define which items go in each part of your suit. You can configure the death effect, creating an explosion with sound and particles.
