LBP Scoring System Analysis & Guide


This guide describes LBP's complex scoring system, from the values of the different ways to earn points, to the formulas of the point reductions from death, to the actual multiplication of combo multipliers, to descriptions and tips about many aspects of the general scoring system.

As of now, there are only three ways to get points: Score bubbles, prize bubbles, and creature brains. There is a fourth way to earn points that comes from rapidly getting/creature-popping any of the game tools that give you points. Likewise, there is only one way to lose points: death. Death does not have a specific point reduction amount, but rather an amount that depends on your score.



Ways To Earn Points & Their Descriptions


Score Bubbles: This is the main way creators give points to the player, because they are small, colorful, and the most obvious way that a player would know is a source of points. The are worth 10 points each.

Prize Bubbles: This is a way to give points that not many creators use, because they are usually tweaked to have prizes inside of them, but it is another liable way to give points. It is worth 50 points, the equivalent of 5 score bubbles, so it can save space or show the player it is a more rewarding, and thus more of an accomplishment to find or get to them.

Creature Brains: This is a way to give points that has the most lenience of the three. Creature brains on creatures or on simple shapes, vulnerable or invulnerable, protected or unprotected, all hand out 50 points, just like a score bubble. The reason creature brains are so different than the other three point types is that they can be triggered from switches. Media Molecule, for example, uses this in their Metal Gear Solid enemies. A 1-shot paint switch destroys the protected creature brains. For this reason, creature brains are often emmited to their deaths in survival challenges whose goals are to survive for the longest amounts of time, and not to pop the most score bubbles.



Combo Multipliers


A combo multiplier is a feature that gives you bonus points if you get many of any combination of score bubbles, prize bubbles, or creature brains in a short amount of time. The maximum time between how fast you obtain any of the things that register into a combo multiplier is about 1 second. Each new point bubble going into a Combo Multiplier has a higher pitch than the last one when popped. A stage of a combo multiplier is a grouping of 5 point-giving objects. Anything less than 5 can be considered a x1 multiplier, so in other words, there would be no in-game animation because it wouldn't make a difference. Once you get 5 or more, but less that 10, you will get a x2 Multiplier.

5 Score Bubbles Gained Separately: 50 Points.
5 Score Bubbles Gained In Quick Succession: 100 points.
This is because 5 Score Bubbles Gained In Quick Succession is a x2 Multiplier, multiplying your score by 2. (50 x 2 = 100.)

6 Score Bubbles Gained Separately: 60 Points.
6 Score Bubbles Gained In Quick Succession: 120 points.
Even though it only takes 5 score bubbles to make a x2 Multiplier, and an additional score bubble won't make a difference to the Multiplier, the additional bubble is still multiplied with the others.

10 Score Bubbles Gained Separately: 100 Points.
10 Score Bubbles Gained In Quick Succession: 300 points.
This is because 10 Score Bubbles Gained In Quick Succession is a x3 Multiplier, multiplying your score by 3. (100 x 2 = 300.) This is an example of a Multiplier that's larger than .2. The same rules still aplly.

10 Score Bubbles Gained Separately: 100 Points.
10 Score Bubbles Gained In Quick Succession: 300 points.
This is because 10 Score Bubbles Gained In Quick Succession is a x3 Multiplier, multiplying your score by 3. (100 x 2 = 300.) This is an example of a Multiplier that's larger than .2. The same rules still aplly.

5 Score Bubbles & 5 Prize BubbleGained Separately: 100 Points. (5 x 10=)50 + (5 x 50=)250 = 300.
5 Score Bubbles & 5 Prize Bubbles Gained In Quick Succession: 900 points.
This is an example of different ways to score points being combined in a x3 Multiplier. The same basic rules still apply, even with the different scoring methods. Separately, they are worth 300 points, but together in a x3 Multiplier, they are worth 900 points.

Two Parts of Combo Multipliers: Combo Multipliers don't just include the points in the multiplier itself, but all points since your last death or last Combo Multiplier. If you pop 10 score bubbles separately, you will get 100 points, as expected. If you then get a x3 multiplier, both the first ten points and new ten points that activated the x3 multiplier are multiplied by 3, together, and added to your previous score.

Using this knowledge, you can make your score much bigger by spreading out multipliers instead of getting a multiplier immediately. However, dying would cancel the Multiplier storage, and you must make sure there is a Multiplier further through the level that can multiply the points since your last multiplier or death.



Point Reduction of Death


Death does not have a specific point reduction value, but a percentage reduction of your current score. Formula:

Death Point Reduction = Current Amount of Points - 5% of Current Amount of Points

For example, if a player has 400 points and then dies, they lose 20 points.

400 x 5%, or 400 x 0.05, = 20.
400 - 20 = 380.
They then have 380 points.

380 x 5%, or 380 x 0.05, = 19.
380 - 19 = 361.
They then have 361 points.

The next number, 361, cannot have 0.05 divided into it without a remainder.
361 x 5%, or 361 x 0.05 = 18.05.
361 - 18.05 = 342.95.

In most traditional math, you would round up 342.95 to 343, but the LBP scoring system only uses the first two digits. The other digits are not recorded with more deaths. To continue the math, you would not take 5% of 342.95. You would take 5% of 342.



Other Information About the Scoring System


-The usual maximum number of points is 1,000,000.
-A 100x Multiplier is the maximum multiplier, which reaches the usual maximum number of points.
-In multiplayer, each new player increases the maximum score by 1,000,000.
-The pie graph in the upper-left corner of multiplayer mode compares players' scores.
-The loud chime noise you hear sometimes means you've beaten a friend's score in a level.

If you haven't already, maybe you should mention that the multiplier sound effect goes to a higher pitch at different levels. You could also write on how the circle that shows your points split in multiplayer and forms a four-way pie graph showing who has the most points (also increasing the max points to 4 million).

Other than that, it's an excellent guide. It's pretty basic information, but not everyone knows it. I didn't know how the death factor worked when it had remainders!

Thanks, and I added your ideas. Is it safe to say that the max score with 3 players is 3 million?

Hey dude, you gorgot something, there IS another way to get score points!
Did you forget there are races as well?

lol, well, just thought i'd mention that since it doesn't seem to appear there.

Could you analyse how scores are worked out for more than one player? I'm trying to build a competitive multiplayer mini-game, and I originally assumed that when one player pops a creature brain then the points are awarded exclusively to that player alone, but I've since figured that the points are evenly distributed among all players in the level. For instance 2 players enter a level, one of them pops a creature brain for 50 points, both reach the exit, but instead of the player who popped the brain getting 1st place, both players are awarded joint 1st place. I'd really like to know if there's a way to use creature brains so that multiple players can compete for points instead of sharing them.2010-05-02 21:35:00

Two things that I didn't notice (I read through quickly):

Creature brains popped off-screen are not subjected to multiplier benefits. What this means is that even if you have a multiplier going, a brain is still worth 50 pts. This was discovered by rtm when working with point-reward payouts. There still needs to be some testing, as it's clear that actively popping creature brains gives a multiplied reward, as illustrated by Brain Chain.

Multipliers are applied to all points collected since last death or multiplier. Collect 10 points not in quick succession, and you'll get 100 points. Collect 5 points not in quick succession and then collect 5 points in quick succession without dying, and you'll get 200 points because the x2 multilpier will apply to all 10 points collected. This is definitely useful if there are a few different multipliers throughout a level, but one of the later ones is worth more.

Consider the following scenario: There are 2 x2's (5 bubbles each, 10 total), 2 x3's (10 bubbles each, 20 total), and a x5 combo (20 bubbles) in a level.

You can either get each combo independently: 100 points for each x2, 300 points for each x3, and 1000 points for the x5. This would give you a total score of 200 + 600 + 1000 = 1800 points.

Else, you can save the combo for the x5 (read: avoiding the x2's and x3's by collecting slowly), and you can get all 80 bubbles with a x5 multiplier, which pays out 4000 points. That is a big difference. It is, however, a risk you must take, in that you have to not die at any point in between.

------

Any point bubble guide must include the above, or else you have failed to understand how the points system actually works.

Cheers.



Edit: It should also be noted that thinking of a death as taking away 5% of the points you have collected thus far is a bit more complex than just understanding that you maintain 95% of the amount you previously had. Thus dying twice is to maintain 95% x 95% of the amount you had, or 90.25%. In general, then, (notice that I am writing percents in a different notation for simplicity) n deaths will result in you maintaining the following fraction of your previously acquired point bubble stash:

Fraction = .95^n

Thus, you just need to raise .95 to the power of however many deaths you encountered. Clearly it becomes more complex as you gain points between deaths, but it should illustrate how dying several times in a row can dramatically affect one's score.

In honesty, there are many bugs with creature brains. I just tested a story mode level with my friend, and if he sat at the side while I popped creature brains, only I would get points. Are you saying you tested the same thing, and the opposite would happen?

There is another strange thing. In some levels, like Nuclearfish's deflectorball, a popped creature brain automatically goes to the game leader. Usually, it divides between all players evenly. I don't understand that.

Another thing I need to test is the division of 50 divided by 4, such as if four players were in a level and a creature brain popped by switch.





Multipliers are applied to all points collected since last death or multiplier.


I definitely didn't know that but I'll add a section.



Fraction = .95^n


I'll add this too. Thanks.

My test involved a switch-activated, self-destructing brain emitter, rather than jumping on creatures to pop their brains. I entered the test level with 2 players, used player one to activate the brain emitter for 50 points, and then took both players to the exit. Both players were awarded joint first position.

I need a set-up where the player one would have come first place in this situation.

Creature brains popped off-screen are not subjected to multiplier benefits.

More specifically, only if they're killed with a one-shot switch.

If an unprotected brain has an emitted paintball fired into it then either...

They are scored AND subjected to the multiplier.
They fail to be be killed at all.

...depending on the phase of the moon (http://www.catb.org/jargon/html/P/phase-of-the-moon.html).

If a vulnerable brain is killed with a hazard, then no points are scored.

Check out the original thread here (https://lbpcentral.lbp-hub.com/index.php?t=23557-Emitters-brains-points-and-lots-of-bugs-().



Thus dying twice is to maintain 95% x 95% of the amount you had, or 95.02%.

I think 95.02% should be 90.25%, alleged math teacher.

Your tutorials never cease to undissapoint me, inc! Many times had I wondered about which was the percentage of points that you lose by death, but finally I do now know it! (a simple 5%... dough!)2010-05-03 03:15:00
