General tip: questions like this go in the help forum, not development assistance

The wiki has a lot of useful information. TPT is a particle simulator toy, pick differing elements and place them together in various configurations to make all sorts of things. You can also browse existing saves to get an idea of the kinds of things that people make.

EDIT: And, yeah, this topic should probably be moved to the help forum. No worries.

Now back on topic, yeah, look at other people's creations to learn how to do stuff

First tip: Don't make silly mistakes like not thinking/reading before you post something. Also, read the wiki and use the search bar before you make any suggestions.
