This is the correct usage of AddStaticVehicleEx

pawn Код:

AddStaticVehicleEx(modelid, Float:spawn_x, Float:spawn_y, Float:spawn_z, Float:angle, color1, color2, respawn_delay);

"respawn_delay" , which means the delay until the car is respawned in seconds.
So you can just add a respawn delay with seconds, or make it AddStaticVehicle if you don't want it to respawn.

CreateVehicle:

pawn Код:

CreateVehicle(modelid, Float:x, Float:y, Float:z, Float:angle, color1, color2, respawn_delay);

You forgot to add color1 and color2.

And about the other warnings, you should show some lines before them so we can see what's the problem.
