In-depth explanation of the score calculation

[ycjy]

Hello!

Christopher here, programmer and 1/2 of YCJY Games.
I have been getting a bunch of questions on how the score is calculated in POST VOID and I will explain in detail how this is done.

Basically it measures how good you play and scores you based on the following variables:

-Time
-Kills
-Head shots
-Levels Cleared
-Accuracy
-Evasion
-Game completion

Let's get over with the most straight-forward stats first:

KILLS & HEAD SHOTS

You get 50 points for every kill. Simple.
Each head shot will grant you and additional 25 points.

LEVELS CLEARED & GAME COMPLETION

Each level cleared gives you 1000 points.
Clearing the game grants you an additional 10 000 points.

TIME

This is a bit more... complicated.
Basically it's calculated per level like this:

round((1-(level time / max time)) * 1000) * 10

level time is the amount of time it took you to complete the level.
max time is a set amount which starts at 35 seconds and gets increased by 5 seconds every act (so 45 seconds in act 3).

example:

if you get a level time of 20 seconds in act 1 you will then get:
((1-(20/35)) * 1000) = 428.57
round that and then multiply with 10 to get 4290. (this is done to get cleaner and more readable scores)

if your time is greater than the max time for the level you get a time bonus of 0 for that level.

All the level scores gets added together when you win or die (When you die, you get no time bonus from the level you died on)

ACCURACY

Accuracy score is calculated like this:

accuracy percentage * 10 * level

so at level 11 with 50% accuracy you would have 50*10*11 = 5500 points.

EVASION

Evasion bonus counts how many times you've been hit and subtracts that from 7 times the amount of levels you have cleared and then multiplies that with 250.

So by level 11 if you get hit over 77 times, you get 0 points for evasion.

One way to (kind of) think about it is that you'd get 1750 points for clearing a level without getting hit! Although you can mess that score up by getting hit more on later levels.

---

So yeah... That's basically it! I hope it makes some amount of sense. It's designed to try to give you more score if you play more skillfully. Time is one of the biggest variables, and if you manage to never get hit it amounts to quite a bit as well!

Feel free to ask me questions here if you have any and I'll try to answer them!

NICE

Useful.
So it's not worth to return and kill missed enemy if it costs you more then 0.2-0.3 seconds.
Good to know.

Ok, I got a question:
Is every shot from shotgun always calculated as miss? Or how it works?

For example:
I carefully completed 1st level with only few misses (accuracy must be 80-90%).
Then selected shotgun and since then almost every shot killed at least 1 enemy.
After dying 2 levels later I expect my overall accuracy near 90%. In fact I got 28%.

Very cool, thanks for explanation!

I just tested and yea, you're (partially) right. All the special weapons don't positively effect accuracy for hits. Only negatively effect it for misses. So in other words your accuracy can only go down after you switch from the pistol. Probably a bug.

maths

[VastleCania]

I'm trying to make a calculator for score in Google Sheets, but I can't quite figure out what I'm missing here. Here's one example of a run where I purposefully completed level 1, then died very quickly afterwards:

Kills: 12 * 50 = 600
Levels completed: 1 * 1000 = 1000
Headshots: 11 * 25 = 275
Accuracy 56 * 10 * 1 = 560
Hits Taken 7 = 0
Finished? no = 0
Totals of above = 2435
Final actual Score = 7985

By this math, I made 5550 points from time alone, but I almost certainly took at least 24 seconds to finish level 1, which should be:

ROUND(((1-(24/35)) * 1000) * 10) = 3143

So obviously I'm missing something here. Any chance you could help me out in figuring out where I messed up the math? Mostly I just want to make this spreadsheet work:

Thanks!!!!

I figured it out!! I had mistaken that Accuracy was based on levels completed - it's based on the level you reached, and same for hits taken. So the new math is:

Kills: 12 * 50 = 600
Levels completed: 1 * 1000 = 1000
Headshots: 11 * 25 = 275
Accuracy 56 * 10 * 2 = 1120
Hits Taken 7 = 1750
Finished? no = 0
Totals of above = 2435
Final actual Score = 7985

Which means I got 3240 for time, or a little under 24 seconds. So that tracks perfectly. The sheet is updated if anyone wants to copy it and use it for themselves

It would be great if that could be confirmed ^. I have noticed abysmal accuracy at the end when the shotgun gets involved. Any dev's about?

I mean it's pretty easy to test it yourself. Go on the first level, and aim to get 50% accuracy by the end of it (headshot an enemy and then shoot a wall right after). Get a special gun on the level transition (restart if you don't). Then, on stage 2, land a bunch of successful shots with the special gun without missing at all, and die. See if your accuracy is still stuck at 50%. It was for me when I tested WAY back then with all the special guns, but the game did get some patches afterwards, so maybe (hopefully) they fixed it since.

EDIT: Screw it, just tested it now with shotgun, uzi, and knife - Knife calculates accuracy perfectly, Uzi and Shotgun are tricky and -seemed- to be a very tiny bit underestimating, but that's probably just from uzi double-fires or individual shotgun pellets still missing even at point blank. Regardless yeah all 3 are able to increase accuracy, so that issue must've been fixed.

The shotgun is gonna tank your accuracy just because every pellet counts, so even if some did hit, the ones that hit walls and what not will still deduct it. You'd need to only be firing it at like point blank to have a chance of it improving your accuracy score.
