When you are naming variables keep couple notes in mind:
1. Only final variables should be in CAPS
2. You start with capital letters only if its a class name
3. You can either use cammelCase or underscore naming: myVar or this: my_var
4. Your variables should have names that are self explanatory example: player_level , xp_counter
5. Avoid using acronyms it recudes readability
6. Have consistency for example if you do this:
if (expression){
// code
}
Keep it do not change it to this:
if (expression)
{
// code
}
and visa versa ofc keep one coding style its easier to from someone to read it.
