Tick

A tick (less commonly spelled tik) refers to a cycle of the program loop of RuneScape, taking 0.6 seconds. Every action that occurs in RuneScape (and by extension, in The Great Orb Project) is synchronized to a tick; when an action is registered in between the beginning of ticks, it will not happen until the beginning of the nearest subsequent tick.

Implications for GOP
The movement of all entities in the Great Orb Project takes place according to the "clock" of tick cycles. Therefore, when performing actions such as movement, clicking orbs, switching wands, and calculating complex angles, the player must keep in mind how their actions must be timed.

For example, if the player is standing at (0,2) and an orb is located at (5,1), if the player clicks the orb, they will be dragged towards (2,0) after one tick. This is due to the fact that the orb's path includes a tile (5,0) that is not within the player's reach. The drag can be avoided by clicking either the ground or the altar after attracting the orb for one tick, and then resuming the attraction of the orb by clicking it the next tick.

A helpful aid to track the tick clock is that when an orb is being manipulated, yellow dots emanate from or to the player once per tick (as do many animations).
