I'm having problem with some codes

[vitorgeller]

Whats up everybody. I'm new here as you can see. I worked in a project and I got some problems with the game codes, I read a lot of post looking for ways to make players run/walk faster, change the spawn point, creating bow sistem and that kind stuff you need change the files in the "src" folder.
As I can see, it worked for everybody but me, I don't know what is going on, I follow correctly each step of the process and nothing changes. I'm using the program called "Dev-C++" to change those codes, I noticed that I can't compile them after replacing something or modifying.
Anyway, I'll be glad If I can change those codes for balancing, modifying and creating a kind of cooperative "Ahriman's Prophecy"

Thanks for your help, and sorry for my bad english  :D
