Im thinking about doing a co-op glitch run with my buddy on xbox but idk what counts as a glitch

@Genesect101 a glitch is a feature the developers didn't intended to be in the game, and in the context can be used to benefit a speedrun. glitches not intentionally caused by the player which aren't exploited or benefited from are not considered glitches.

for example, using item duplication exploits will make a run 'glitched', but running past a sheep that spawned stuck in a grass block is glitchless. It depends on whether a glitch is performed intentionally, and if and how much it benefits the run.

it's also worth noting that glitches must be performed in order for a run to qualify as glitched, and many glitches also require playing on a specific game patch.

I hope this answers your question, it's quite broad and not entirely black and white in a speedrunning context.

So does xray count?

No

So will me digging into a wall and using sand to xray to find a treasure chest count towards a glitch run?

yes because in that case it is intentional if you accidently x-rayed for a second it would still be glitchless

okay thank you for the help
