How to make a gust push a door and a chair?

[Russ Money]

How? I am trying to make it more creepier for my story, how?

Scripting.

Here are the funcs

For the chair
AddPropImpulse("chair", 0, 0, 0, "world");

The three 0's are the cords for the X, Y, Z axis. "chair" is name of the entity and "world" is the CordSystem, you normally want to leave it as "world".

For the door, it's the same
AddPropImpulse("door", 0, 0, 0, "world");

You'll want to add the impulse on which way it opens.
Example: If the door swings open towards the X axis, increasingly, it'll be something like this:

AddPropImpulse("door", 0.8f, 0, 0, "world");
