I am now starting to develop a game and I occasionally look online for snippets/Tutorials on how I would do a certain function that I was stuck on. Then I modify as needed or improve. My question is: Are there any specific laws I should be worried about when programming?

Disclaimer: IANAL

The laws you need to worry about when programming are copyright and patent laws.

When you copy code you've found somewhere, copyright law is the one that applies. Unfortunately many sources don't clearly state under which circumstance the copyright is waived, so you can ask or guess...

If you modify code, it's basically a derivative work, which is also covered by copyright to some extent.

Note that these sorts of copyright breaches are extremely hard to prove... (see SCO vs. Novell)
