Is there something I could use in non-render things. I need like a Minecraft.getPartialTick

Why?

There is no "smaller" thing than tick (as said partial ones are for rendering) when talking about minecraft-proper coding.

Probably only way to achieve this would require you to have synchronized (and self-correcting) mod-timer that would work along with minecraft's timer (where 50ms = 1 tick).

 

It IS obviously possible (been there, done that) but you would have to handle synchronizations on your own, and more importantly - system would be no more useful than TickEvent (because it wouldn't be really possible to "guess" when is the right time to call method with it).

 

Verdict: Don't do that (in probably any case).

 

P.S - you might be interested in mod that allows users to "record" world in means of "action-recording".

Action-recording - you can watch record from any perspective in given tick.

Why? I am not sure, but I belive they managed to extend ticks to more-than-20 per second (or something similar), at least, that's what they were working on few months ago. Probably ASM stuff tho

Isnt there some kind of hackery I could do with getSystemTime to find how far between the game is between ticks when calculating something?

Again, why? What are you trying to accomplish that doesn't work on full ticks?

Its not really rendering, its just I have something that needs its movement updated (MORE) than 20 times a second. Im thinking the best way is to have a method that gets its position for that instant in time using a partial tick to get the effect that its constantly being updated. Similar to what the rendering does the entities but Im trying to extend that to the logic too. This would be used on both client and server in the end.

 

Anyway how can I check how far between ticks I am?

Here m8, since your so inclined:

When in between ticks the rendered outline will spaz out because the players hit vector updates every render(not tick), but the intercept Bounding Box is getting calculated on the old position and the result is the selected block will switch stupidly between ticks because only the hit vector got updated every frame.

 

Now plz how do I fix it

 

Edit: I cant achieve this by updating a number every time it gets a frame either because I need the tick server side too since its still handling collisions
