I am using the Wolfram Engine 12.2 and Unity 2020.3.3f1 on Windows 10 20H2. When I try to open the roll-a-ball example I get several error messages.

In[3]:= <<UnityLink`

In[4]:= UnityOpen["ExampleData/roll-a-ball"]

Syntax::com: Warning: comma encountered with no adjacent expression. The expression will be treated as Null. (line 469 of "C:\Users\janme\AppData\Roaming\WolframEngine\Paclets\Repository\UnityLin k-2020.02.02\Kernel\UnityAssets.m").

Hi Jan.

I'm a n00b, but I've found you need to activate Unitylink first . In your example << is "Get" not "Needs" EDIT Since writing this I've seen that Get seems to be synonymous with Needs, but even so, try it this way and let us know.

Needs["UnityLink`"]

and then

UnityOpen["ExampleData/roll-a-ball"]
