You have to download the file, unpack it, then put it in your scripts/game/command folder for your mod. Afterwards, you open up the editor, go to "Mods", click on the mod you put the script in. It will ask you some stuff, say yes, then you will have to wait... a variable amount of time. I have a bad computer and it takes 1 to 2 mins. Then go to "Map" -> Load Map. (click no when it asks to save the map) It will give a dialog with the em4 main folder open, look for the Maps folder. Open and select freeplay.e4m . This is the freeplay map file. Once you finish that left click on any building you want to add the enter house command to. Then click the "Properties" button on the bottom of the screen. Find "child-objects", it is right next to the icon of your building. Click on the checkmark box for the child referencing the enter house script. If it's there, then you need to add the script command to personnel, unfortunaly that is something complicated that I don't like whatsoever. I cannot help you there. If the editor crashes, maybe it's your computer. Or you may need admin powers on your computer. If the child for the enter house command is not there, then you will need to redownload or make sure the file is in the right place. Remember to save the map at "Map" -> "Save"! But a better option is to download a mod that already has the script pre- installed, like the Mayberry Mod, for people like you who aren't up to the editor or don't understand it. Have fun, edit hard, learn a lot, and drink a soda! And this is only what I can see from looking at the topic. I might have gotten it a bit wrong around the rough edges.
