Is it possible to interlock a vehicle into a double block on Sandbox? I tried to do this with placing a gaus warthog on a platform, then deleting the platform and setting the warthog on spawn at start no. Then I started a new round and placed the double block, but the warthog just appeared on top of it :< . I saw a tutorial that let you forge vehicles inside map geometry but I can't do that because I'm using the skybubble.
Honestly, I don't think this is possible. An immovable object like a vehicle CAN NOT be interlocked, unless you have the block spawn 10 seconds in. Only when the vehicle is settled you can use this.
If you want to do this for aesthetics only then you can. Set a block on a horizontal surface. Take whatever vehicle you want interlocked and drive it pushing the MOVABLE object out of the way. When the block resets and you have your vehicle where it spawns to it should be interlocked. however you cannot shoot or touch it.
