ZDoom

Checking it in P_FindLineSpecial makes more sense because it covers all eventualities.

That's because [url=https://github.com/coelckers/gzdoom/blob/6ff6a6af002b1f46bd50524fb9da16b460f1a333/src/p_lnspec.cpp#L3897]P_FindLineSpecial()[/url] knows nothing about [url=https://github.com/coelckers/gzdoom/blob/6ff6a6af002b1f46bd50524fb9da16b460f1a333/src/scripting/backend/codegen.cpp#L7768]TeleportSpecial -> Teleport[/url] aliasing.
Not sure, is it better to extend the function or just add an extra condition at [url=https://github.com/coelckers/gzdoom/blob/6ff6a6af002b1f46bd50524fb9da16b460f1a333/src/scripting/zscript/zcc_compile.cpp#L2999]its call site[/url]?

BLAH A 35 TeleportSpecial(1, 0, 0);

TeleportSpecial: action function not found in <name_of_calling_actor_class>

BLAH A 35 { TeleportSpecial(1, 0, 0); }

Remember [url=https://forum.zdoom.org/viewtopic.php?f=7&t=59239]this[/url]? Yeah, when calling that special directly from a state, like this:

[code]BLAH A 35 TeleportSpecial(1, 0, 0);[/code]
GZDoom aborts on launch with this error:

[code]TeleportSpecial: action function not found in <name_of_calling_actor_class>[/code]
If I wrap the call to the special in a function, I don't get any errors:

[code]BLAH A 35 { TeleportSpecial(1, 0, 0); }[/code]
