This time there was one important exported script function: Actor.Spawn.
Since this will require a level pointer in the new scheme of things the old version had to be deprecated, because it is static with no argument that allows retrieving the level. However, since this is probably one of the most widely used functions I added a workaround to let it continue to work if used from inside an actor class, which should constitute >95% of all uses. This required a little bit of hackery in the compiler backend to swap out the function if appropriate.
Aside from that there were 5 places in the internal ZScript that needed handling, which mostly consisted of making a formerly static internal function non-static.
Many uses of random() & value have been turned into random(0, value).
This is not only more efficient, it also ensures better random distribution because the parameter-less variant only returns values between 0 and 255.
- fixed emission of the self pointer in FxVMFunctionCall. I did not realize that the self expression only sets up a register for the value, not pushing it onto the stack.
