Usage Rules

There are 4 rules that affect where you will end up after teleport estate access rule telehub rule parcel access rule parcel landing point rule

Teleporting follows visibility/access rules. You can teleport to places visible on the world map (exception - if the region you are on has "Mainland Visible from Here = NO", you may still be able to teleport to places you cannot see on the world map)

Teleporting rules: Estate access = NO

  • teleport fails with error message

Estate access = YES

  • P2P = OFF
    • TH is present
      • Go to nearest TH on estate, (to a random spawn point?)
    • TH is not present
      • Follow parcel's landing point rules
          • If no landing point rules, arrive directly at your target.

If in god mode, invited by a god, teleporting home, Died

  • Go directly to the target location, bypassing estate, telehub, and parcel rules

If teleport invited

  • Follow estate rule, bypass TH rule, follow Parcel landing point rule

(Expand explaination when estates w/ different P2P configurations are adjacent)

(Explain what a "safe" alternate region is, how it is determined, how often it is determined, and what it's used for)

(Teleport to a location underground, near ground, in the air. What is your animation state?)

When you teleport arrive:

  • What do you look like to you?
  • What do you look like to observers?

Facing direction: You should face direction the landing point has set. If no landing point, you should be facing your target
