Hi, can you add hooks for spawn/despawn cars for override result it ?

Yes, I'm planning to implement various hooks.

I can provide better support if you can you provide more info about your use case. For instance, are you primarily concerned with blocking the cars spawned directly by players via this plugin, or if this plugin were being used as an API, would you also want to block other plugins from spawning cars via this plugin? Also curious why you would want to block despawning.

For example, there is a special zone where the classic mode, and if the player drove into it, the despawn will not work.

Why don't you want the despawn to work in that particular zone? All despawning currently does is destroy the vehicle. How would having a vehicle disappear affect your game mode?

Various hooks were implemented in 3.1.0 to allow blocking commands.
