With permission from the Phoenix mod team (thanks Erayser ) Stargazer and I have been trying to wrap our heads around their Stargate mod shield system and create a hybrid with our Star Trek: Continuum shield system. Their shield system is visually superior to ours as it uses a subsystem for the shield itself and (with the use of non-penetration secondary hit fx) allows for different hit fx on the shield and on the ship hull if you have the collision meshes all correct. Our scripting system makes our shields functionally superior to theirs though as we can have the shields drop to 0% health when ships cloak, we only had subsystems to fake a shield health bar.
The main drawback to their subsystem method is that you can have weapons on the ships blocked from firing by the subsystem collision mesh, even though the joints are outside that collision mesh. The trick is that this subsystem collision mesh substitutes for the ship collision mesh to block the weapons from hitting the ship collision mesh and triggering the alternate hit effect, which is the whole point of trying to go down this path.
There is a better way though, can we please have a flag on a subsystem to allow the ship that itâs mounted on to ignore the subsystem collision mesh? So that a shipâs own beams, pulses and torpedoes/missiles will pass through it unmolested?
This will mean that we can simply have the sphereoid shield collision mesh in the subsystem, the non-penetrate fx as the shield hit fx and the hit fx as the hull hit fx. Using the âspawn weapons fire on hitâ functionality we can spawn a sphere-burst weapon with no FX to apply the damage to the shields while still allowing the non-penetrate fx to be played correctly when the weapon hits the hull. If the subsystem is set to damageable then the shield will be destroyed, fail and after a short time start to regenerate. Multiple mods would benefit from this simplification of the shield mechanics, the rest of the issue is just attack and armour families
Allowing effects and animations for subsystems would also allow us to put shield fail FX into a subsystem âeventsâ file directly instead of scripting it in elsewhere, just set the on/off animation to play when the shield system hits 1% health, have the collision mesh for the shield move up 10000m out of the way so the shipâs hull can be hit and youâre covered! Currently we just move the joint that the shield is mounted on, but having this in the subsystem itself could simplify things
So, to summarise, my request distils down to three items:
Flag in subsystem file to allow ship that its mounted on to ignore the subsystem collision mesh and fire any weapon through it without triggering any FX or interrupting missiles
Allow an events file for subsystems in the same fashion as there is one for ships
Allow an animation for subsystems so we can move the collision mesh up when the subsystem health is 0
I canât make any promises - nor can I work on this right now regardless (kinda busy with that whole HW1/HW2/Formations thing) - but this is noted. Some of this can be done pretty fast. Other things I think maybe can be done a better way, which will be covered once itâs ready to show off
Iâd like to definitely second this request- also having a subsystemâs collision mesh be removed when it hits 0 health would also be very nice to see- instead of moving the joint/mesh.
Thank you @BitVenom! Itâs good to know this is on the list
I agree with @tempest6677, If thereâs a flag âNewSubSystemType.IsShieldâ with a 0 or 1 value to cover the blocking of collisions for the weapons of the host ship and auto-remove the collision mesh when the subsystem hits 0 health that would be fantastic! Two birds with one flag
Youâd have to assume NewSubSystemType.IsShield = 0 if thereâs no entry in the .subs file for it too, so it doesnât muck up all the other .subs files out there
I would be so grateful for proper shield support if it ever comes
The CM based shields were a nightmare and I eventually abandoned them for the current subsystem regen combo
I can come up with dozens of thoughts on how to do shields and what I would need for various scenarios, but if there was any way to integrate the functionality into a ship file rather than a subsystem that would be awesome
They have conformal shields in most cases so really it would be the visual hit effect change when the shield is down rather than a bubble. Most of the shipâs longevity is in the shields and armor is really a last ditch defense. Strike craft ordinance provide the easiest method to damage subsystems and cause earlier shield failure with precision attacks. I would also want a certain amount of bleed through based on weapon class vs a shield class as well as having some weapons ignore the shields entirely/partially.
Without a subsystem collision mesh to allow the ânon penetrationâ alternate hit fx to be triggered I am not sure how youâd go about getting an FX change on the weapons.
It still seems to me like youâd benefit from the same proposed system, youâd just use a much tighter collision mesh on the subsystem.
note: I have written a horribly crappy implementation of âAwesomeTriPickRaycastUWlogicâ before and I really mean it when I say âgrossly simplifiedâ
another reason I really donât want to use subsystems for the shields is that I have some 19km long triangles that donât play well with collision meshes as it is and subsystems just make that issue infinitely worse.
I also was hoping to be able to implement shields without resorting to subs. We already have a complicated mess and I didnât really want to add to it. Having to redo ship and weapons templates for exports would also be a big pain⌠but good, working shields with different hit effects would definitely be worth the pain of revising the templates.
The Original SoA mod (Homeworld Classic) used âfake shieldsâ. There really were no shields, but there was a shield hit effect. We figured if shields were down that the ship would blow up with one, or 2 hits anyway. So we just combined shield, and hull into total hit points.
Hi all, sorry to necro this thread, 526 days after it died, but all the pertinent points are here
I had a thought on changing the armour family of a ship during a game, and thusly allowing shield AND hull hit FX on demand.
If my thought turns out to be right of course.
Exhibit A:
*\ship\tai_gravwellgenerator\singleplayer\props\default.lua, line 9, âDockFamily = âControllerâ,â
Exhibit B:
*\ship\tai_gravwellgenerator\singleplayer\props\default.lua, line 6, âString_Properties_Priority = 1.0â
The Dock Family is set in the string properties section of the file, which means that the armour family could be set there too. Theoretically, anything in the ship file could be set in this section or in the Number_Properties section.
Now, if there is a conflict between this and something else then the section with the highest priority number wins! The big question is can we change this number at will? Say⌠when a subsystem is destroyed? (Ignoring the fact that ships still canât shoot through their own subsystem collision meshes).
If the armour family changes a set of weapons with the hull hit FX will then be able to hit the ship and the initial set of weapons that have the shield hit fx would then be unable to hit the ship. One of the ugliest parts of the existing shield solution would be summarily dealt with!
So, can the String_Properties_Priority number for a ship be changed? Or even brought into conflict to force one or the other being applied?
@bitvenom, the higher priority âdefaultâ in the rules file is ignored and the hull hit FX are played on the ship, even though the normal Heavy Armour family with the shield hit FX should be in force.
Iâve not even got to trying to change the priority value yet
In this case, if the rule has a setting, it replaces the one specified by the ship (or lacking both, the default of HeavyArmour is used)⌠The ship script is lua - you can do ârealâ work in it⌠you could make a table in the ship file of armor types, and just have the rule set a value (like an int or enum) that uses the table only in certain cases, etc. Go crazy!
