So idk, if everyone know it already, but you can make decorations with physics, like a pot on the window.
I don't know what to say next, so i'll just write down trigger code (gun and decoration are required):
uid: #trigger*[number]
enabled: true
maxcalls: -1
SetGunSlot( "#gun*[number]", "666" );
SetGunForVehicles( "#gun*[number]", "0" );
op172( "#gun*[number]", "0" );
SetGunPower( "#gun*[number]", "0" );
SetGunProjectileCount( "#gun*[number]", "0" );
op300( "#decor*[number]", "#gun*[number]" );
That's all, it's the end of tutorial, bye.
