Just imported the package into 2018.1, and tried to build, getting this error:
RichAI.cs(502, 23): [CS0103] The name `animCompatibility' does not exist in the current context
RichAI.cs(502, 50): [CS0103] The name `anim' does not exist in the current context
RichAI.cs(502, 57): [CS0103] The name `animCompatibility' does not exist in the current context
animCompatibility
and anim
are variables that aren’t defined or referenced anywhere else.
Commenting out the override method that lines is in makes the project build.
