"AI_Eye" (Ver.1.1)

This object is placed under "AI_Core" in AI tanks, and is used for searching the enemy tanks.
"AI_Control_CS" script in the "AI_Core" casts a ray from this object to detect the target.

The position of this object is very important for detecting the target.
When this position is too low, the AI cannot detect any target because the searching ray has been obstructed by its collider.
