Counts the length of time the player has been jumping. The counter increments from 0 (not jumping) up to 1441 as follows:
0 181 361 541 721 901 1081 1261 1441
Once it reaches 1441, it will reset to 0 and the player will begin falling.
NOTE: In water surface sectors LOTAG 1, the counter will only reach up to 901.
You can use this counter to limit or extend the height of the player's jump.
