Open Source

The Unreal Wiki is making tentative inroads to acting as repository of open source UnrealScript. It's been pointed out that open source stuff might be better running on a different script with different features, which could run alongside the Wiki script on this site. If you are interested in the creation or adaptation of such a script, make yourself known here or on Project Aims and Project Discussion.

There are a lot of misconceptions about Open Source going around. One of them is that Open Source would be free of copyright; it's not, and far from it. Every bit of Open Source software is copyrighted and comes with a license. Sometimes that license says that you can use the code at will. In any case, you're bound to adhere to whatever licensing terms come with the code. The individual original authors of the samples listed below might have different stances on that, so read the accompanying statements carefully.
