The walkable slope angle
The walkable slope angle is the maximum slope on which an agent can walk. If the slope
angle is set too high, our agents will attempt to walk on inclines where gravity and friction
will cause them to stop or fall backwards. Our default soldier agent can travel over inclines
as steep as 45 degrees, based on their maximum speed and acceleration.
A navigation mesh with a walkable slope angle of 45.0 degrees
By default, our navigation mesh is generated to allow angles up to but not exceeding 45 de-
grees, as shown in the previous screenshot. Setting the walkable slope angle to a much
smaller value—for instance, 15 degrees—will prevent navmesh from being generated on
the exact same ramp.
