An advancement of the project has come. Ever since the week learning different times of animations, I figured a way round the train level without the earlier issues. If I animate everything else, the background, the floor and objects around the train the player is in. The engine will not glitch up with collisions while keeping the illusion of a moving level. Animation is the key to making the whole level move along.
The train assets can be used to build in the level now and aren’t wasted after all.
Train level consists of a few assets that are built for background use such as towers and buildings, billboards and fences.
