Physics only works when close to the driving line? | Forums

[Euphoric Fusion]

I came across a problem last night when making my next level. Whether it is a bug or a performance trade off i don't know so I thought I would post it here to see if one of the devs can answer for sure.
Let me explain.
My latest track is called "Shipyard" and starts out in a warehouse for building boats then moves outside to the docks. In the background at the finish line I wanted a rotating light that simulated a lighthouse so I made a simple version to test. I used a roof lamp, free rotation hinge, a vertical piece of straight pipe and a dynamite box. The box explodes when triggered about 20m from the finish which makes the light start to spin round making it look like a lighthouse lamp.
Now it worked perfectly when I tested it on the driving line to see if I would get the right effect and I thought it was awesome.
BUT....
When I moved the structure to the background, about 2-3 floor squares away from the driving line the dynamite no longer affected the lamp. The box exploded but the light just stayed stationary.
It seems that triggers can effect the breaking of objects, the turning on of lights and everything else but won't physically interact with other objects if it is too far from the driving line.
Is this how the game engine works or did I do something wrong?

Only physics objects that are close enough to the bike are simulated. Others are not. This is done to improve game performance (frame rate).

I thought that would be the case. Thanks for clearing that up

How close?

I'd say no more than 2 floor tiles away.
