Is there a way to check for button / keyboard input with GS?

[Openend]

Ive looked through the documentation and (so far) 4 other gamescripts, but not found the answer yet.

Is there a way to listen for input from the main game within a game script, to trigger a function for example, when the player presses a button or a key?

No.

You can use the query dialog which has up to 3 buttons from a set of pre defined captions. You can listen for the event when one of those are pressed. You will get the event at company level, so if many persons play at the same company, you'll see them all as one user. Thus the first one to click will win, but they do have team chat so they can talk among each other and decide what to do. After all many people on a single company will be in a cooperating team and not compete against each other.

A second option you have is to scan signs of companies and look for some sign commands. Eg. if a player create a sign with the text "!money" you can look for such signs once a while and when it is found, you remove it and give them money using the API for that.

Thanks, that was what I needed. I was looking for a way to test changes quickly, for example, if I create a function to grow a city, I can trigger it fast and easy with this. Do you have more advise on quick tests of gamescripts?

Enable gui.ai_developer_tools so you get the break-on-log-message feature as well as AIController::Break() to add a break point inside your code.

Edit: you may also check out the sign related helpers in SuperLib. Some of them are older than the debugging support in OpenTTD, but may still be of use depending on what fit you. As you may be aware of, when writing a GS, use GSCompanyMode to specify as which company you want to access signs etc.

Thanks! Ill play with this and report back if I stumble again
