| Summary | 0004233: Transported aircraft becomes (magically) unattached and takes damage from transport despite allowUnitCollisionDamage = false | ||||||||
| Description | I can't be sure this is entirely an engine issue, though I have done my best to eliminate any issues game side. The game is particularly lua-heavy and disabling lua rules is not really an option for testing as the situation to replicate is entirely bound up in the game mechanics. All units in MCL are delivered by transports, this works fine for ground units and 'gunship' aircraft, but regular aircraft somehow come 'unattached' before they should (when dropship decelerates when landing) and take damage. UnitPreDamaged reports a weaponDefID of -3 meaning unit-unit collision damage, but Modrules.lua has allowUnitCollisionDamage = false (which is the default anyway) In short there are 2 questions; 1. Why do the aircraft become unattached when they should not? 2. Why do they take unit collision damage when it is disabled? | ||||||||
| Steps To Reproduce | 1. Get MCL - currently not on rapid, but SVN only, apologies for the inconvenience: svn://svn.code.sf.net/p/mwspring/code/ 2. Start a game on a supported map http://sourceforge.net/p/mwspring/code/HEAD/tree/maps/flagConfig/ (I suggest Koom Valley v2 http://springfiles.com/spring/spring-maps/koom-valley ) 3. Select the Drop Zone unit on your starting beacon (ring of blinky lights) 4. Click the 'aero' button in the menu, then click the buildpic for IS_sparrowhawk, then click "Submit Order" button. After 20 seconds (edit http://sourceforge.net/p/mwspring/code/HEAD/tree/LuaRules/Gadgets/unit_purchasing.lua#l42 if you want to reduce for testing) dropship will be spawned and fall towards your drop zone 5. Just after there is the "ROCKET FULL BURN NOW!" "GEAR DEPLOYING..." message the vtol unit will come unattached and start to take damage. | ||||||||
| Additional Information | The un-attachment is most likely triggered by applying negative gravity to the transport: http://sourceforge.net/p/mwspring/code/HEAD/tree/scripts/Dropship_FX.lua#l197 There's a UnitPreDamaged call at: http://sourceforge.net/p/mwspring/code/HEAD/tree/LuaRules/Gadgets/game_radar.lua#l119 If you need it for testing | ||||||||

By 'unattached' I mean the transport drops / unloads the passenger. Forgot to mention: The transports themselves are spawned by lua, moved to a great height and given a downwards velocity via MoveCtrl then decelerated by -ve gravity as previously stated. Video here: https://www.dropbox.com/s/dnn5hzr4oz9t0bq/3%20-%20Dropship%20Delivery.wmv Takes you through ordering system but it should be fairly self explanatory |

fyi: the transporter (with aircraft loaded) is movectrl'ed. |
