it's only for some maps. it seems like it's for the harder ones? I tried snow note's inbachi and rizia's mafumafu revenge, but I also tried byakuya gensoutan extra diffs and my own Seashore on the moon, all of them crashed the visualizer. maybe it's only my visualizer. even for maps that were not that difficult sometimes it would crash.

Some ISkill.CalculateDifficulty() implementations have side effects which would cause a different result to return if called a second time.

eg. Volatility recovery in DimensionalSkill.CalculateEnergyExertion() (which is called from PhysicalSkill.CalculateDifficulty())

These lines with side effects should be refactored to be done within ProcessHitObject() instead

For some reason it appears adding HR to plays when testing in the visualiser, reading difficulty is always zero.

Investigate why this is happening.

General

• Implement stacking
• Implement slider curves
• Move skill multiplier to difficulty point level rather than totaling

Aiming

• Initial balance
• Slider support
• Shortcut detection algorithm
• Spacing changes impact on difficulty?
• Snappiness threshold scaling with exertion
• Replace angles with momentum system for semantic difficulty

Clicking

• Initial balance
• Rhythm complexity based on fluctuations in timing scaled with OD? OD as base?

Reading

• Initial balance
• Slider support?
• Overlap function of some sort to replace normalised distances?
• Bonus to click reading for low AR

Visualiser

• Rewrite completely with support for any calculator built with the framework (will require framework modifications and probably reflection magic)
• Add "watch osu!" functionality to recalculate when saving a map in the editor?

Score

• Contemplate effects of reading difficulty

Performance/Skill points

• Create project

Not started

• Taiko difficulty calculator
• Catch difficulty calculator
• Mania difficulty calculator
• Standard touchscreen difficulty calculator

90 degree angles with -1 snappiness give only a 0.5 bonus which seems rather low for their actual difficulty.

An idea is to use a logarithmic curve instead of a sine curve for objects with low snappiness.
