10 Anatomy of a slider

Sliders are quite complex objects, and behave differently over different implementations. This page aims to track the current state of sliders with the end goal of unifying/improving behaviour.

Portions which differ on lazer are highlighted in bold.

	stable	lazer
Head
Judgement	Hit window is equal to a hit50	Act as a normal hit circle with full judgement range
Scoring	hit=30 miss=0	hit=300(Great)/100(Good)/50(Meh) + combo_bonus miss=0
Combo	hit=+1 miss=reset
Tick
Judgement	At precise point in time
Scoring	hit=10 miss=0	hit=30(LargeTick) + combo_bonus miss=0
Combo	hit=+1 miss=reset
Repeat
Judgement	At precise point in time
Scoring	hit=30 miss=0	hit=30(LargeTick) + combo_bonus miss=0
Combo	hit=+1 miss=reset
Tail
Judgement	Occurs exactly min(36, slider_duration / 2)ms before end of slider	Occurs at any point in the last 36ms of the slider
Scoring	hit=300/100/50 depending on tick count miss=0	hit=10(SmallTick) + combo_bonus miss=0
Combo	hit=+1 miss=reset	hit=0 miss=0

Summarising the current differences in slider behaviour which are not unanimously accepted, in order of importance:

• Tail doesn't give combo on lazer. This leads to max combo discrepancies on all beatmaps. (In addition, tail gives a combo even on a miss with classic mod applied)
• Combo bonus is added to ticks/repeats where it wasn't on stable. This can lead to score discrepancies based on hit ordering.
• Ticks give less score on stable when compared to lazer. Not sure how much this matters.
