(svn r5594) Be more strict what's allowed to be built in a hangar: if the airport can't handle planes/helicopters don't present and disallow building planes/helicopters - the latter case wasn't covered yet.
Also remove an error message about building aircraft which can't be triggered by a normal client
Scripting
---------
OpenTTD supports scripts.
local scripts:
- 'autoexec.scr' is executed on gamestart [all - use this for custom aliases per ex.]
+network scripts:
should be used to set client optimization settings:
- 'on_client.scr' is executed when you join a server [all clients]
should be used to set the servers port/ip and/or server optimization settings/patches:
- 'pre_server.scr' is executed before the servers tcp stack is started [in-game only]
- 'pre_dedicated.scr' is executed before the servers tcp stack is started [dedicated only]
should be used to set the servers name, password and so on:
- 'on_server.scr' is executed after starting a server [dedicated and in-game]
- 'on_dedicated.scr' is additionally executed after starting a server [dedicated only]
For examples how a script can look, check the .example examples.
