Scripts:EvalPy

What It Does

• Allows you to test snippets of Python code while the server is running, without having to restart it to load changes from files.

Installation

1. Browse to admin/standard_admin in your bf2 server directory
2. Edit __init__.py so it looks something like the code snippet below.
3. Save the below code to admin/standard_admin/eval.py.
4. Make sure RCON is configured, then run your server. If "eval.py loaded" comes up in your server console it should work from there.

This doesn't work from the server console. You'll have to use an actual RCON client to use the command this script creates. The remoteconsole.py script should work just fine.

The command is "eval [statement]". An example would be something like the following:

rcon> eval for i in dir(bf2.objectManager.getObjectsOfTemplate('c4_explosives')[0]): ctx.write(str(i) + '\n')

Which then might return:

__doc__
getChildren
getParent
getPosition
getRotation
getTemplateProperty
hasArmor
isControlPoint
isPlayerControlObject
isValid
setPosition
setRotation
templateName
token

Note: Be extra careful when using ctx.write() over RCON. Though I have the script set to catch all exceptions, giving ctx.write() a non-string will still cause an exception. Failure to take this into account can cause RCON to die completely. Using ctx.write(str(variable)) should keep you safe.

Code

__init__.py

import autobalance
import tk_punish
import eval

autobalance.init()
tk_punish.init()
eval.init()
