Slow Thread for loading

So i’m after a way to create a thread that slowly loads items that will be used later in the program. I’m not after specifics more of just an idea of how to create such a thread that can be set to do so. I tried to make a thread with min priority, also was thinking of making the thread sleep for a second then run for a second until it is all loaded. I feel like this is a really noobish question and any input would be appreciated! thanks :slight_smile:
