rP24010: Improve splash damage falloff calculation to account for obstruction size.

Summary

As noted in D2759, splash calculates falloff based on centre-to-point distance, which is somewhat incorrect -> it ought to use nearest-edge-to-point distance.

This:

cleans up GetUnitSize for just GetSize (unrelated in this iteration of the patch but I noticed it while working on this)
Uses DistanceToPoint to calculate an exact distance for falloff
Makes sure the damage multiplier cannot be below 0.

The change to DistanceToPoint might be controversial - it's certainly slower, but for buildings it's required.

Test Plan

Check that the new maths is correct and agree that this new behaviour is preferable.

wraitii requested review of this revision.Aug 17 2020, 1:04 PM

Good use of those range functions imo.

Some small stuffs, otherwise good to go:

./source/simulation2/components/tests/test_ObstructionManager.h has a GetUnitRadius reference. Straightforward nuke

binaries/data/mods/public/simulation/components/Trader.js
301 ↗	(On Diff #13219)	could add spaces while at it
binaries/data/mods/public/simulation/components/tests/test_Builder.js
80 ↗	(On Diff #13219)	can nuke a `.0` while at it
binaries/data/mods/public/simulation/components/tests/test_Damage.js
207 ↗	(On Diff #13219)	Make the linter happy, by quoting the object keys
209 ↗	(On Diff #13219)	weird that the linter doesn't complain about trailing comma's
303 ↗	(On Diff #13219)	Please some linter
binaries/data/mods/public/simulation/helpers/Attacking.js
310 ↗	(On Diff #13219)	I believe this reason not to be accurate. The reason it can become negative is the rangemanager returning to many to far away entities (due to square/circular shape mismatch)

This revision is now accepted and ready to land.Aug 25 2020, 1:55 PM

wraitii added inline comments.Aug 27 2020, 9:38 AM

binaries/data/mods/public/simulation/helpers/Attacking.js
310 ↗	(On Diff #13219)	Mh, that's kind of what I meant here. I'll clarify.

@bb's comments + Rebased.

Will commit once lights are green.
