Firstly, due to the industry background, the life cycle system had to be updated. For example, 1 crab has a total energy bubble of 1000 According to the 100% mining to calculate, the average 1 team an activity gain 150 (the current simple calculation does not consider the detailed mathematical expectations), 1 crab consumption 4 energy bubbles gain 50TUS, Calculated 1000/4*50=12500TUS average day consumption of 24 energy bubbles is expected to end 41.66 days According to the calculation of 100% looting, the average win rate of a team is calculated according to 80%, one crab consumes 1 energy bubble gain 50TUS, calculated 1000/4*50=12,500TUS. Calculated 1000 * 50 = 50,000 TUS. According to 50% mining 50% looting to calculate, it is expected that a crab earnings in 6250 + 25000 = 31250 Considering that if players are lying flat mining, the return may be very low, but considering that the life cycle can not be too long, so the design in 2000 energy bubble is more reasonable, at this time the crab life cycle is expected to end 83 days is more reasonable. The end of the life cycle does not mean that the crab has no value, can be pve and future competitive mode, of course, can add a back to rebuild function After starting the rebuild, one of the following results will be generated (options can be adjusted according to the content of the later game iterations). Rebirth: regain 2000 energy bubbles Probability: 10% Return to life: 200 energy bubbles Probability: 20% mutation: parts have a probability of progression into legendary parts crab, but does not increase the energy bubbles Probability: 5% (Late) converted into runes: according to the rarity of runes to adjust the probability Probability: 35% Extinction: turn into ashes, only increase 100 experience value. Probability: 30% Summary purpose: to put an end to crabs infinite life early players pose bad, to put an end to crab population inflation, I hope the project side according to the above content reference serious research design a reasonable life health cycle system.
