TPS ranged weapon

Hello! I recently made a post where I asked how to find the rate of fire in the code of a ranged weapon (mcreator 1.12.2) and they told me that it was possibly related to the TPS, but I don't know how to use it or how to find it or anything, the only thing that I know, it's related to ticks.

Does anyone know what I could do with that? because I want to make an assault rifle but it shoots very slow (I activated shoot constantly)

Thanks! (the previous post is still there, in case any programmer wants to see it).
