File talk:Spawning requirements.png

i play all vertions of minecraft and i find that mobs spawn in lit up areas i mean zombies skelitons and creepers me and my freind got killed after sleeping on xbox and lost 30 diamonds this must be fixed in a future xbox udate

Is this image suggesting that a mob can spawn inside of solid transparent blocks? What exactly is meant by 'unobstructed'? 67.85.116.221 04:00, 20 July 2013 (UTC)

Wither Skeletons
This diagram does not cover the fact that wither skeletons can spawn in a 1x1x2 area despite their bounding box being larger. Clearly their bounding box is obstructed, but they spawn anyway. 124.188.145.99 19:50, 1 January 2013 (UTC)
