CEL AI Navigation

Introduction

celNavigationTools it's part of celtool that makes a bunch of useful operations for navigation.

You need to choose Navigator - entity with pcmesh and tracked Target - vector, other entity or map mode.

Then information is returned to celNavigationInfo or choosed variables in blxml:

bool success - if everything is ok, entity exists, target exist etc.
bool visible - if target is visible
float distance - distance between navigator and target
vector3 angle - angle between navigator and target (note it's angle between point-point in worldspace, it omits direction vectors)

Determine track by placing nodes on the map. Name that objects for example "node1" "node2" etc. Usualy the best way to do this is making spline/bezier and automatically duplicate nodes on this.
Make in your level loader creating trigger for every node.
In every AI loop step (1/10s for example) set Navigator to car entity, and target to map node "node"+current_node_nr. This number should be increased after reaching node trigger.
Now check what celNavigationInfo says. If distance is far than car can move fast.
