Setting up monster routes

Monster routes are controlled through the use of path nodes (type 9024). A path node ignores its special and assigns special meaning to its arguments; the first argument identifies the next node in the path, and the second argument specifies how long (in seconds) a monster should wait at this node before proceeding to the next one. Because special arguments are only one byte in size, you are effectively limited to 255 path nodes per map. Hopefully this won't be a problem.

To set a monster on a path, you have two options: use the Thing_SetGoal special in a script or on a line to send a monster or group of monsters to a node, or set a monster's special to Thing_SetGoal. If a monster's special is Thing_SetGoal, and the tid specified for the special is 0, the monster will be sent to the node automatically when the level is loaded, and its special will be ignored if it dies.
