XCOM Explosive Damage Destroys Corpses Development Notes
Revision as of 04:06, 17 November 2018 by Dubiousintent (talk | contribs) (Added 'Category:Mod_Creation')
Overview
This article describes the information discovered while developing the Explosive Damage Mods.
Purpose of this modlet is to allow the options for aliens that are killed by explosions to have their corpses destroyed.
Details
Weapon Fragments are computed:
- XGTacticalGameCore.GenerateWeaponFragments computes the amount.
- Alien Grenade : 4 (0 for Long War)
- Plasma Pistol : 8 (1 for Long War)
- L. Plasma Rifle : 8 (1 for Long War)
- Plasma Rifle : 12 (1 for Long War)
- Cyberdisc Weapon : 16 (2 for Long War)
- Drone Beam : 4 (0 for Long War)
- Heavy Plasma : 20 (2 for Long War)
- Sectopod Chest Cannon : 24 (3 for Long War)
This is then float multiplied by the FragmentBalance DGC.ini variable (=0.13 for Long War)
- GenerateWeaponFragments is called in XGUnit.CheckForDamagedItems.
It is only called if the unit is !IsMine() && !m_bKilledByExplosion
- The Weapon Fragments are then stored in the BattleDesc.m_arrArtifacts
- This is controlled in XGSummaryUI.CollectArtifactsFromDeadAliens
There is also the call:
- class'XComCollectible'.static.CollectCollectibles(m_kDesc.m_arrArtifacts);
made in XGBattle during state 'Done' -- unfortunately this is a native function
