General encouragement:
You can pick a lot of animations off the marketplace that will get you by.
When it comes to specific animations, it may get a little bit more difficult, which is when <insert 3d graphics program comes in>.
Ifs your primarily focused on designing a game that involves building/construction, focus on that first.
No point having pretty animations and nice models if the basics don’t work
