Since Miarmy 3.5, we added terrain color perception logic. Now the agent can feel the color of the ground and also the gradient of the color.
With these tools we can achieve:
the color intensity of my position Return 0~1 based on the intensity of ground color in position
more darker on LEFT/RIGHT
more darker in FRONT/BACK
Support there are 4 agents on terrain in 4 positions and feel different gradient of the texture color
All agents face same direction just different position
