Paths in [[GTA_4|GTA IV]] are similar to the 64 node-files introduced with [[GTA_SA|San Andreas]]. Like the first version of the format there are 64 node files where each file corresponds to a 750x750 square unit starting with <code>nodes0.nod</code> in the south-west corner (-3000.0, -3000.0) and ending in the north-east corner (3000.0, 3000.0) of the game's world in [[Wikipedia:row-major order|row-major order]].

==Preamble==

Before trying to understand the format of GTA IV's path files, it is recommended to read the [[Paths (GTA SA)|San Andreas paths]] article, since GTA IV paths are an update of the old format.

Unlike San Andreas, paths are not stored in the major [[archive file]] ([[gta3.img]]) and the node files also do not have the extension <code>.dat</code> anymore. In GTA IV, paths are stored in the <code>~\pc\data\cdimages\paths.[[img]]</code> file as 64 <code>.nod</code> files. Furthermore the file structure has generally changed: If San Andreas had 7 sections per node file, GTA IV only got 2. Linking works in a different way and there are no navi nodes any longer.

{{Incomplete}}

==File Format==

The following data types and structures are used within this article:
* '''INT8/UINT8''' - signed/unsigned 8 bit integer ''(1 byte)''
* '''INT16/UINT16''' - signed/unsigned 16 bit integer ''(2 byte)''
* '''INT32/UINT32''' - signed/unsigned 32 bit integer ''(4 byte)''
* '''FLOAT''' - single precision floating point number ''(4 byte)''

===Header===

The header is a structure of 4 values with a size of 16 bytes.

4b - UINT32 - Number of nodes ([[Paths_(GTA4)#Section_1_-_Nodes|section 1]])
4b - UINT32 - Number of car-nodes
4b - UINT32 - Number of intersection nodes
4b - UINT32 - Number of links ([[Paths_(GTA4)#Section_2_-_Links|section 2]])

{{Incomplete}}

===Section 1 - Nodes===

4b - UINT32 - MemAddress
4b - UINT32 - Zero (Allways)
2b - UINT16 - Area ID
2b - UINT16 - Node ID
4b - UINT32 - Unknown - may be related into [[GTA_SA_Paths#Section_2_-_Navi_Nodes|interpolation]]
2b - UINT16 - Allways 0x7FFE
2b - UINT16 - LinkID
6b - INT16[3] - Position (XYZ)
1b - BYTE - Path Width
1b - BYTE - Path Type
4b - UINT32 - Flags

;Area ID: defines the area where the node lays in. Usually this is the same number as the one of the node file.
;Node ID: defines the id of the node. This is important for linking the node to others. Using the node and area id nodes can be identified as unique. There cannot be 2 nodes with the same area ''and'' node id.

;Link ID: points to an link in section 2. The link ID cannot point into another node file. It points to a link in the same node file. However this link is able to point to an node in another or the same area.
;Position (X,Y,Z): The world-coordinates of the node. To get the floating point X and Y coordinates divide the 16 bit integer by 8. For Z coords you have to divide by 128 (Unlike San Andreas).
;Path Width: used to set the width of the paths. For cars this is related in how much space there is between 2 lanes. Divide the 8 bit unsigned integer by 8 to get the floating point value.
;Path Type: descripes the type of an node. This is used to isolate certain nodes from others. For boats this is allways 0x01.
;Flags: the flags are used to influence the behaviour of non-person-characters (NPC's), which are spawned along the paths on the nodes (See below).

====Path Node Flags====

0-4: unknown

Flag 05: Emergency only
Flag 06: Boats
Flag 07: Unknown
Flag 08: Exactly the same as 05
Flag 09: Intersection central node
Flag 10: Is highway
Flag 11: Is not highway

12-15: Link count

Flag 16: Disable linking

17-23: unknown (Perhaps related to lanes or other earlier [[GTA_SA_Paths#Navi_Node_Flags|Navi node flags]])

Flag 24: Is ped node?
Flag 25: Rarely used, police controls or roadblocks?
Flag 26: unknown ped flag
Flag 27: Unknown ped flag

28-31: unknown

* ''Structure unconfirmed and partially incomplete''

{{Incomplete}}

===Section 2 - Links===

2b - UINT16 - Area ID
2b - UINT16 - Node ID
1b - UINT8 - Unknown
1b - UINT8 - Link length
2b - UINT16 - Flags

* ''Structure unconfirmed and partially incomplete''
