I tryed to find any tutorial how to add dinos like managarms and other dinos in to game.ini but i didn't find any .

can anyone help me ?

To add dinosaurs to a map, you have to know which spawner to add them to.

Refer to

https://ark.gamepedia.com/SpawnMap(Valguero)

for where certain dinos spawn, you'll see the name of each spawner

Such as "VALTwitchFertileLandMix" being the spawner where roll rats spawn.

Ok and then after i found the spawner locations what should i put in my game.ini?

You'll need to either create an override (to completely replace everything in that spawner with what you want) or an add block.

For instance, this is the ini line for changing all the dinosaurs in the castle in ragnarok to the Nameless spawn:

ConfigOverrideNPCSpawnEntriesContainer=(NPCSpawnEntriesContainerClassString="DinoSpawnEntriesTinyCave", NPCSpawnEntries=((AnEntryName="ChupaSpawn",EntryWeight=0.5,NPCsToSpawnStrings=("ChupaCabraCharacterBPC"))),NPCSpawnLimits=((NPCClassString="ChupaCabraCharacterBPC",MaxPercentageOfDesiredNumToAllow=0.99)))

I would refer to the ARK wiki for specifics as it's not a basic or advanced command, and will take multiple balance passes if you're wanting to use

ConfigAddNPCSpawnEntriesContainer instead of ConfigOverrideNPCSpawnEntriesContainer
