unity3d 2dtools - Make an endless 2D map in Unity -

basically, idea game this: have rocket launch ground, , keep adding speed. rises higher , higher, want camera follow rocket, , can move rocket pick special objects , avoid obstacles. how create endless map in unity, rocket won't fly off map. thank you!

// singleton. translates existing obstacles , creates additional obstacles. 

// world moves around player.

// when object collided into, level pieces deactivated. // level ends when level pieces deactivated

i used awhile ago.

levelparent gameobject. make empty go. endlesslevelobject_prefabs... put in level pieces want spawn

lastcreatedobject. set first level piece.
