The only way for this to work would be to somehow “unlink” the created debris from the root so that when destroy_root is called the debris still keep on living for their defined period of time.

Thinking about this, I remembered a specific incident where a piece of debris survived the root explosion. Or at the least, that what it appears to have happened. Luckily I just happened to have it on video.

Click image for video link.

After the Bretonian Destroyer is destroyed, it goes through its death fuse, and and what is presumably the root is destroyed by the end of it. However a piece is still left over. You can see the big loop piece just sitting there after the ship has been completely destroyed.

It’s very possible that may only have happened because of the way Freelancer splits up its models, (the method you were specifically avoiding) but that’s the only lead I can give.

Ya, that’s exactly what we wanted. Well, lets hope one of the gurus of FL can figure this one out. If not, it’s back to the drawing board.

Just to add:

Three things must happen in sequential order; the explosion, the swapping of the main model for the wrecked model and finally, the separation of the parts.

Control over speed and direction of the wrecked pieces is part two of the [d]problem[/d] challenge.:-)

The “holes” in the model seen are my fault and will be corrected shortly.

@ why: isnt that a random mission solar rather than a wreck? capship solars in mission regularly leave debris destroying only the root. Seems to be control by fate = debris line in the main fuse. I like where this is going, always thought it was a bit rubbish having an indestructable wreck

So I talked to Dev and he recommended we try a different way. I’ll post the code here so everyone can follow. Sadly, we don’t get a result at all and we’re both at a loss as to why:

This is the code in our solararch/shiparch:

fuse = mc90_wreck, 0.000000, 1
-----------------------
[CollisionGroup]
obj = debris_zomgbayz01
separable = true
debris_type = debris_mc90_wreck_forward
hit_pts = 10000
root_health_proxy = false

[CollisionGroup]
obj = debris_zomgbayz02
separable = true
debris_type = debris_mc90_wreck_main
hit_pts = 10000
root_health_proxy = false

[CollisionGroup]
obj = debris_zomgbayz03
separable = true
debris_type = debris_mc90_wreck_rear
hit_pts = 10000
root_health_proxy = false

This links to both the explosion.ini and fuse.ini

[destroy_root]

Considering the other way worked, I’m at a loss to why this method doesn’t and was wondering if anyone could shed some light on the topic.

Thanks for all the help thus far, fellas.

Yay double post

So I attached the hardpoints to the collision groups (debris_zomgbayz01, 02 and 03) and was able to get the debris render. It even continued to render after the root was destroyed. FF and I are currently working on getting the debris to move properly and we’re hoping we’ll have good results from that as it’s somewhat erratic at the moment. More updates to follow, hopefully.

Gisteron

i’d suggest to add impulses to the fuse to get the wrecks moving. also more realistic if nearby objects unaffiliated with the ship get thrown away a bit, too. about the wreckages and root, another idea would make the root a dummy object which you have enough of in your cmp (hopefully this suggestion had not been made making me a careless reader xD)

FriendlyFire

Impulse blocks don’t seem to work in fuses.

We’ve already tried.

foxUnit01

Have you tried increasing the debris_impulse lines in the Explosion entry? If the pieces are of high mass, 100 impulse won’t really do much.

FriendlyFire

Problem is that those only affect the debris created after the CollisionGroups are destroyed. These debris are always created at 0,0,0 on the root and tend to fly in odd patterns, which doesn’t look good at all when you have debris over 2k long.

The hard part is making the debris that spawn directly from the fuse look good.
