Is there a way to make a sign display the players name?
Yeah, just include the value of global.player_name in the message.
Easiest way would probably be to make a new type of signpost (a child of the obj_signpost so it "just works" with the existing interaction code) whose interact_script is cis_npc_polyliner and then give it a new expression-typed variable "my_messages". For each sign you place you'd then give it a messages value like:
[tsprintf("This is %'s house!",global.player_name)]
(So it contains an array of strings, with only 1 value - this is different from just a regular string, since cis_npc_polyliner loops over the array of messages, so don't forget the []'s around it)
(The reason the default signpost doesn't work is that it has a string-type variable, so it'll just include the variable / tsprintf call as text instead of running the code. You could of course change it to expression-type in the base sign instead, but that breaks all existing signposts unless you manually add quotation marks around their text...)
i get this when i do what you sugested.
Instance Code in Room: rm_overworld_5 at line 1 : invalid token '
Undefined variable 'This' referenced in room rm_overworld in instance inst_16EAE0C0's variable 'my_message'
Undefined variable 'is' referenced in room rm_overworld in instance inst_16EAE0C0's variable 'my_message'
Did you:
- turn it into an Expression variable?
- put quotes (") around the text?
- put square brackets ([ at the start, ] at the end) around the resulting string?
The error message makes it sound like it's trying to interpret plaintext (the stuff that's supposed to be in a string) as an expression so it sounds like you missed the quotes.
