Arena spawns in the side of a tall mountain on a custom map

As you can see in the screenshot the Arena is spawning in the side of a tall mountain on Wonder Foxes Custom Map Kamo island.

Is there a way to make the arena spawn ALOT higher in the sky? Because currently it spawns in mountain sides then players spawn inside of the rock and get stuck

Set it to spawn higher with ggsetcentrepoint

 

I don’t understand all the numbers how to change it a few 300m higher? What numbers would I use 

can you make the config simpler to say like 300meters to adjust by the meters ? 

If I want it to be say 800 Meters in the sky what would I make these numbers?

{
  "centrePoint": {
    "x": 20.24202,
    "y": 123.753609,
    "z": 78.2398

Use the command. It will adjust the positions.

Fly to the location/height that you want the event to be at and run the command ggsetcentrepoint <arena name>
