Animated whooping crane. Follows waypoints, or wanders around within a certain distance of the spawn point (controlled by range[e] value in line 51 of the script, 1000 by default).
Flies away if you get too close (alert range is controlled by the alertDistance[e] variable in line 68 of the script, 50 by default).
Soaring height is controlled by the soarHeight[e] variable (line 65), and the time spent on the various idle states (idle, feeding and walking) is controlled by the idleTime[e] variable (line 67), 10000 by default (the time is milliseconds, so 10000 is 10 seconds).
2 LOD stages.
Can be killed, but only when it is on the ground.
Script makes provision for wing flap sound (not included). Name your sound birdflap.ogg and place in the files-audiobank-misc folder.
Available in the 'Storks, cranes, herons etc' pack, seen in the video.
