Well the other programmer who quit the project told me I HAD to make sure I got their types right and he used to be a professional programmer. I guess he's living in the past. I just was curious if it'd have an accumulative effect of specifying the wrong type for variables by the end of my game's production or not when I have like 10,000 variables. This is because I noticed he also did stuff like used for each loops wrong everywhere in the code that really impacted performance. So I was kinda doubting him but wanted to be 100% sure.
For the sake of convenience though I will be sure their types are correctly set.
