City.spawnCar firsts argument is a Draft according to the docs, but it isn't

[FranchuFranchu]

Take a look at the attachment, and place the new building next to a road. The Lua code leaves an error in log.txt

It seems that the first argument should be a Java object, but of course you can't make Java objects in Lua.

@Lobby?

...pretty sure this doesnt belong to plugin errors

Thank you, I did an implementation mistake on the Java side of things. The documentation is correct, but the current implementation expects an actual draft object as it can be obtained by draft.orig (that is some sort of Lua representation for Java objects).

So in your example using

Code: Select all

City.spawnCar(h.orig, ...)

should solve the issue. I'll make that code compatible with a future bugfix.
