Contributions to MTA: SA Source Code
The contribution I am most proud of is givePedWeapon client side as it allowed us to hack fix server side peds and have client side missions.
Some of the newer commits: https://github.com/multitheftauto/mtasa-blue/commits?author=ArranTuna
But my biggest contributions to the source code is all the testing, bug reporting and mantis organising that allowed the wonderful and gifted MTA developers to have more time doing what they do best.
Contributions to The Wiki
Documented 74 of the functions and events and many other things like a lot of the Changes in X (which I started with Changes_in_1.1) over these past 8 great years.
