Summary0023118: Melee Logic Tweak
DescriptionMelee still have a problem in regards to failing to hit moving targets. Here is a potential suggestion to alleviate that.

Old -
bool setMoveToEnemy = true;

int kiteDistance = -1;
for ( int i = 0; i < entity.Systems.Count; i++ )
{
    EntitySystem system = entity.Systems[i];
    if ( system.DataForMark.CalculateActualRange( system.ParentEntity ) >= 124000 ) //Range of Artillery Golem
    {
        setMoveToEnemy = false;
        kiteDistance = system.GetKitingDistance( targetEnemyEntity );
        break;
    }
    if ( !system.GetCanHitAssumingItIsEnemy( targetEnemyEntity, true ) )
        continue;
    if ( kiteDistance < 0 )
    {
        kiteDistance = system.GetKitingDistance( targetEnemyEntity );
    }
    else
        kiteDistance = Math.Min( kiteDistance, system.GetKitingDistance( targetEnemyEntity ) );
}
Regular Chasing & Kiting Logic...

New -
bool setMoveToEnemy = true;
bool isMelee = false;
int kiteDistance = -1;
for ( int i = 0; i < entity.Systems.Count; i++ )
{
    EntitySystem system = entity.Systems[i];
    int range = system.DataForMark.CalculateActualRange( system.ParentEntity );
    if ( system.TypeData.IsMelee ) //Melee
    {
        isMelee = true;
        break;
    }
    else if ( range >= 124000 ) //Range of Artillery Golem
    {
        setMoveToEnemy = false;
        kiteDistance = system.GetKitingDistance( targetEnemyEntity );
        break;
    }
    if ( !system.GetCanHitAssumingItIsEnemy( targetEnemyEntity, true ) )
        continue;
    if ( kiteDistance < 0 )
    {
        kiteDistance = system.GetKitingDistance( targetEnemyEntity );
    }
    else
        kiteDistance = Math.Min( kiteDistance, system.GetKitingDistance( targetEnemyEntity ) );
}

// If melee, always try to move into melee range.
if ( isMelee )
{
    if ( targetEnemyEntity.FramePlan_Move_NextMovePoint != ArcenPoint.ZeroZeroPoint )
        targetDest = targetEnemyEntity.FramePlan_Move_NextMovePoint;
    else
        targetDest = targetEnemyEntity.WorldLocation;
} else {

So this
     if ( targetEnemyEntity.FramePlan_Move_NextMovePoint != ArcenPoint.ZeroZeroPoint )
        targetDest = targetEnemyEntity.FramePlan_Move_NextMovePoint;

is a potential source of races, but it's not clear that it will cause problems.

You have source access though. Have you tested this?

Yes sir; it has caused melee to correctly hit targets moving away from themselves, and has not caused any hanging or performance degradation as far as I can tell.

Didn't want to push it to source without prior approval considering its a sim change. Any minor errors there could cause a cascading effect.

Update - Swapped the range check for an isMelee check due to things like cloaking triggering it with their range of 0.

Old-
if ( range <= 300 ) //Melee
New-
if ( system.TypeData.IsMelee ) //Melee

I doubt chris is going to push to steam, so I'd say go ahead and check it in and we'll see.

If you want to be paranoid, gate the logic behind a Setting

Pushed in behind a setting; thanks for the suggestion Badger.

First of all - great stuff. This new logic seems to be working flawlessly.

That said, I'm not sure you've committed it correctly. I see that steamdb reports depot changes, wiki says this was introduced in 2.023 and the ingame behavior has certainly changed (much to the better!)... but the settings toggle option is missing. I would assume that the merged logic is now on by default instead of being available as an option.

Just in case: Main menu reports 2.024, checked *all* settings menus both in and out of proper gameplay, and checked galaxy settings in a newly generated game in case it only showed up there. It's MIA on all of them. No settings toggle.

So it turns out that I forgot a field that allows the setting to show mid-save. It will correctly show in the lobby; but no longer appear after the game has started. Whoops. Will nudge that in for the next update.

This seems to be fixed now, by starkelp
