Simple Matchmaking
Simple rule based matchmaking for your online game with support of Redcon(RESP) protocol.
1- Simple Match Rule
Easiest usage of system is "Direct Match Rule" in this rule players match each other without any rule.
package main
import (
"github.com/fatihkahveci/simple-matchmaking/matchmaking"
"github.com/fatihkahveci/simple-matchmaking/server"
"github.com/fatihkahveci/simple-matchmaking/store"
"time"
)
func main() {
inMemory := store.NewInMemoryStore()
dur, _ := time.ParseDuration("10s")
r := matchmaking.NewDirectMatchRule()
respServer := server.NewRespServer(inMemory, ":1234")
matcher := matchmaking.NewMatchmaking("test",respServer,inMemory, r, dur)
matcher.Start()
}
2- Score Match Rule
In this example users match with given score rule which means match happens only user score 10 between 15.
package main
import (
"github.com/fatihkahveci/simple-matchmaking"
"github.com/fatihkahveci/simple-matchmaking/rules"
"github.com/fatihkahveci/simple-matchmaking/server"
"github.com/fatihkahveci/simple-matchmaking/store"
"time"
)
func main() {
inMemory := store.NewInMemoryStore()
dur, _ :=time.ParseDuration("10s")
r := rules.NewScoreMatchRule(10,15)
respServer := server.NewRespServer(inMemory, ":1234")
matcher := simpe_mm.NewMatchmaking("score",respServer,inMemory, r, dur)
matcher.Start()
}
3- Custom Match Rule
In this example we create our own rule. We just need to follow "MatchRule" interface.
= minLevel && user2Level <= maxLevel {
return true
}
return false
}
func (r CustomFieldMatchRule) GetName() string {
return "CustomField"
}
func main() {
inMemory := store.NewInMemoryStore()
dur, _ :=time.ParseDuration("10s")
r := NewCustomFieldMatchRule("level",10,20)
respServer := server.NewRespServer(inMemory, ":1234")
matcher := simpe_mm.NewMatchmaking("custom",respServer,inMemory, r, dur)
matcher.Start()
}
">
package main
import (
"github.com/fatihkahveci/simple-matchmaking"
"github.com/fatihkahveci/simple-matchmaking/server"
"github.com/fatihkahveci/simple-matchmaking/store"
"time"
)
type CustomFieldMatchRule struct {
Field string
MinThreshold int
MaxThreshold int
}
func NewCustomFieldMatchRule(field string,minThreshold, maxThreshold int) CustomFieldMatchRule {
return CustomFieldMatchRule{
Field: field,
MinThreshold: minThreshold,
MaxThreshold: maxThreshold,
}
}
func (r CustomFieldMatchRule) Match(user1, user2 store.User) bool {
user1Level := user1.Fields[r.Field].(int)
user2Level := user2.Fields[r.Field].(int)
minLevel := user1Level - r.MinThreshold
maxLevel := user1Level + r.MaxThreshold
if user2Level >= minLevel && user2Level <= maxLevel {
return true
}
return false
}
func (r CustomFieldMatchRule) GetName() string {
return "CustomField"
}
func main() {
inMemory := store.NewInMemoryStore()
dur, _ :=time.ParseDuration("10s")
r := NewCustomFieldMatchRule("level",10,20)
respServer := server.NewRespServer(inMemory, ":1234")
matcher := simpe_mm.NewMatchmaking("custom",respServer,inMemory, r, dur)
matcher.Start()
}
Usage
You can add new user to pool using any redis client. Thanks for Redcon
redis-cli -p 1234 add '{
"id": "55",
"score": 5
}'
Also you need to subscribe your matchmaking channel.
redis-cli -p 1234
127.0.0.1:1234> subscribe simple
Reading messages... (press Ctrl-C to quit)
1) "subscribe"
2) "simple"
3) (integer) 1
1) "message"
2) "simple"
3) "{\"user_1\":{\"id\":\"12\",\"score\":5,\"join_time\":\"2021-08-31T22:57:27.109609+03:00\",\"fields\":null},\"user_2\":{\"id\":\"55\",\"score\":5,\"join_time\":\"2021-08-31T22:57:27.109614+03:00\",\"fields\":null},\"match_rule_name\":\"Direct\",\"time\":\"2021-08-31T22:57:27.116724+03:00\",\"action_type\":\"match\"}"
TODOS
- More Server Support (WebSocket etc)
- More Store Support (Redis, Mongo etc)
- Multiple User Support (Team matchmaking)
