Boundaries

Boundaries are a feature in games that prevent the player from advancing past a certain point to prevent crashing and bugging out. In Pixelshift, there are limits depending on the behaviour of certain objects or variables.

X axis (positive and negative)
Along the X axis, there is a set boundary of 4 million pixels due to the teleportation command loading the block numbers needed to generate terrain at a certain distance. When 4 million is exceeded, the game takes 2x longer to generate terrain.

If the player attempts to exceed 4 million, they'll be stopped from going further and turn invisible, causing them to f all to their death.

Y axis (positive)
Going an excessive height on the Y axis is impossible to pull off without cheats, but there are some adverse effects while going upwards beyond millions. Nothing else happens beyond 113 million, unless someone discovers something else.
 * At 37,785,500 height, the terrain vanishes, leaving the background only.
 * At 107,374,000 height, the terrain glitches in and out of existence. If the player is not on a black line or the terrain itself, the terrain will vanish. If the player is touching terrain, the terrain will flash infinitely. If the player goes any higher, blocks will cease to exist until the player travels below this limit.
 * At 113,356,000 height, the background vanishes, leaving nothing but black.
