! rowspan="2" class="unsortable" style="text-align: center" | Task
** var names
! rowspan="2" | Exec Environment
** format, indentation, no one-line, spacing, line returns
! rowspan="1" colspan="5" class="unsortable" | Machine
** Be consistent (space/tab indentation, (camel)casing, K&R / Allman style indenting. See [https://en.wikipedia.org/wiki/Indentation_style#K&R_style Indentation Styles])

* Don't duplicate, make functions
! Single Player
* prefix your public variables with your tag
! Dedicated Server
* PRIVATE (or params) your variables
! Hosted Server
* Use #define SOME_CONST for constant values instead of variables
! Multiplayer Client
! [[Multiplayer Scripting#Join In Progress|JIP]] MP Client

  1. ↑ isPlayer _entity does not return true immediately. Once the entity has become a player, it is transferred to the client.
  2. ↑ 2.0 2.1 Note in single player that while the environment is Scheduled (canSuspend returns true), the engine seems to wait until the script is done executing, essentially behaving similarly to an Unscheduled environment - infinite loops will freeze the game, uiSleep may pause the game for up to ~20s (postInit), waitUntil can cause catastrophic issues, etc.
  3. ↑ player is not available immediately.
