Q: Will there be a client side? A: Yes, there will be a full-fledged client side with the ability to run your own code.
Q: Will it be possible to add your own models to the game? A: This is not planned in the first versions, it is possible in the future.
Q: In what language is it possible to program your modifications? A: There will be an SDK for C++, with which you can create your own plugins. The plugin will already be able to load what you want. For the convenience of the community with SA-MP, I will personally develop a plugin for loading Pawn scripts.
Q: Will there be a built-in anti-cheat? A: Not in the very first versions, in the future the server will filter garbage information and check the compliance of all player properties. If the information coming from the client does not match the one set by the developer, the corresponding callback will be called. The developer will be able to decide the future of the player himself.
Q: Limits on spawn? A: At the moment I am engaged in reverse engineering, I can't name the limits for sure yet.
Q: Maximum online? A: Since the maximum online depends on the number of players that the player can see, there is again the question of limits. I can't give an answer at the moment. This information will be updated soon.
