OTClient How its works?

[SalvaART]

Hello, I wanted to ask more experienced users how exactly the following process works:

How to exactly replace sprits from 8.6 to 7.4 in otclient and how does it interact with the map later? Converting the map from 7.4 to 8.6 gives me red boxes because the IDs are changed, how to recreate the real 7.4 map on the 8.6 server with the 8.6 protocol?

When i trying replace spr and dat 7.4 with 8.6 when i login on server i got black screen ingame.

Thanks for any help.

It depends on the base you are using and the 7.4 map of course, it is best to use the downgrade map from the following post:

[7.72] RealOTX with CastSystem - OpenSource

Hello Otlanders, i am here to present my project Open Source, Real Open Tibia Server based on Protocol 7.72 As you can see, I like the open source. I think this project to make the best Real Open Tibia 7.72 with your help. Would you help me? ;) You can make your own pull request and help this...

otland.net

so you can use the map, items.otb (need made some changes in sources to work properly), and then u can use 7.7 .dat and .spr converted to 8.60 on any server 8.60 like GitHub - nekiro/TFS-1.5-Downgrades at 8.60 (https://github.com/nekiro/TFS-1.5-Downgrades/tree/8.60)


Also keep in mind that you will have to review the quest mechanics, movements, etc. So that your map is completely compatible and functional in all its aspects in the new base, since it will not just be replacing files.

Thanks for your help, i can use this map ofc but what i need to do next? i need open this map in RME and convert from 7.72 to 8.60 and save it?

The most important thing is, what Base are you using?

After converting the .dat and .spr to 8.60, you need to make the items compatible as well. Just like the map. But you don't necessarily need to convert the map you can continue using the 7.7 map and the itgems as it comes. You only have to replace the load of the items as well as the map in the sources.
