'''PATH''' is a section in the [[item placement]] file in [[Vice City]]. It is used to define paths for traffic. Paths are grouped into nodes, each with at most 12 sub-nodes. The group nodes define the type of vehicle going to be used by the sub nodes. Sub nodes contain path coordinates which are linked to each other. There are two kinds of links:
 +
* internal links – connecting nodes within the same group.
 +
* external links – connecting nodes over two different groups.

Paths in Vice City are grouped into nodes, each with at most 12 sub-nodes. The Group nodes define the type of vehicle going to be used by the sub nodes. Sub nodes contain path coordinates which are linked to each other both internally(Inside the group) and externally(Outside the group with other group nodes).

First of all, consider a small segment of the line in a group node. The group node has to be defined and then there are the 12 sub-nodes inside it. The number of coordinates vary from 2 to 12. If the number of coordinates does not reach 12, then they are filled with null nodes which does not do anything just to make the group node hold always 12 nodes. The internal and external sub nodes are defined each with a special attribute in it. The internal sub nodes are the middle parts of a segment of the line, while the external sub nodes are the end points of the segment of the line. They are used to connect to other external sub-node or end point of another segment(Another group) of the line. To connect the external sub-nodes or end points, they must and always must have the same coordinates. All the other group nodes link up together using this concept, thus you get a path which a vehicle or a ped follows from the beginning and to the end of the line.

PATH is a section in the item placement file in Vice City. It is used to define paths for traffic. Paths are grouped into nodes, each with at most 12 sub-nodes. The group nodes define the type of vehicle going to be used by the sub nodes. Sub nodes contain path coordinates which are linked to each other. There are two kinds of links:

  • internal links – connecting nodes within the same group.
  • external links – connecting nodes over two different groups.

Description

Car Paths Visualization
Ped Paths Visualization

Consider a small segment of the line in vehicle paths node. The group has to be defined and then there must be 12 nodes inside it. If the total number of internal and external nodes in a group is not 12, then the remaining should be filled with null nodes.

The internal nodes define the connections inside the group whereas the external nodes define the connections to other group. External nodes in a group are connected to other external nodes in different group external sub-nodes by having the same coordinates.

Spawns are always made in internal nodes, and external nodes only act as a link. For vehicles, lane information and the median width inside internal nodes are ignored, those information are only retrieved from external nodes. And also for vehicles, junctions are always kept in a separate group and external nodes of the group must always point to beginning of a connected line segment, whereas pedestrian nodes can mix the two.

One can add a maximum of 4 paths group in Vice City though this limit can be increased by Maxorator's Path hacks. [1]
