i'm using libgdx draw 2d scene. before drawing this: batch.setprojectionmatrix(camera.combined); as expected, (0,0) coordinates no longer in bottom left of screen, @ middle of screen. what more elegant solution position whole scene correctly: 1) translate/position camera accordingly show that's on screen. 2) draw while having in mind (0,0) @ middle now, so: batch.draw(background, -background.getregionwidth()/2, -background.getregionheight()/2); note i'm doing parallax scrolling , first option dispositions midground layer objects bit, expected. if there no solution problem, i'm leaning more towards second option. try keep objects in "world space" , keep translations "world space" screen in "camera" (the "camera" abstraction around matrices defined translate world space screen space). polluting object's locations information screen cause confusion , problems. specifically, in case, call camera.t...
