Goals of successful MMOG

• encourage exploration
• resources distribution
• unfamiliar
• world replication

Approach

generate game worlds based on previously defined set of rules joining the benefits of procedural generation with manual art work creation

Approach

• world
• blocks
• connectors

Approach

Approach

• world based constraints
• block based constraints

Approach

Approach

Modular

• rule-based-map-generator
• blocker

Approach

rule-based-map-generator

• world generation
• constraint satisfaction
• handles world expansions seamlessly
• multiple strategies
• pluggable rules

Approach

blocker

• network layer on top of rule-based-map-generator
• communication between the server and its clients
• event based communication
• multiple rooms

Case study

H1Z1 game

• open-world survival MMO game
• explore to collect resources
• survive enemies and other players
• take advantage of buildings
• points of interest are well distributed

Blocks

Case study - World definition

world constraints

• initial size: 10 units
• horizontal boundaries: 40 units
• vertical boundaries: 40 units
• map center: vehicles spawn

Case study - World definition

block constraints

• Car spawning locations are apart from other car spawn locations by at least 10 map units and apart from gas stations by at least 7 map units
• Gas station are apart from other gas station by at least 5 units
• ... Water wells should be in short number so they should be no more than 3% of the whole map Gas stations should be in short number so they should be no more than 1% of the whole map -->

Conclusions

Strengths

• reduce development effort
• flexible
• different needs
• room to improve
• different contexts

Conclusions

possible extensions

• blocks with different sizes
• more communication protocols
• decision besides seed value
