Actually I was very wrong. There is no way the biochamber will output its fuel as part of any signal. Almost any current solution is prone to breaking at some point due to spoilage.

Use a filtered inserter for the legendary nutrients. Wire it to the assembler. Read the assembler contents and only enable your legendary when theer are already normal nutrients in the assembler.

Thanks for the example showing what I was missing. This is now fixed for the next release.

Before it was working like this:

Wall has 350 health
Medium asteroid hits wall wanting to do 100 damage
Wall takes 33~ damage due to resistances
Asteroid records "33 damage used to impact wall" and ...

Wow this is handy and did not know you could do it this way.

Ok, this one is a little weird. Here's the code for explosion remnant particles. This is the debris left over by an explosion.
{
type = "particle",
name = "explosion-remnants-particle",
flags = {"not-on-map"},
life_time = 60 * 15,
pictures =

filename = "__base__/graphics/entity ...

Bah, I'd just started writing an asteroid plugin, but it looks like you're already much further on than me so I'll stop. Regarding ore amount, I have no idea how to solve that issue. Although... What if the asteroid exploded in to several smaller asteroids which themselves deposit iron?

Are you ...

First time post here. Trying to make an asteroid that crashes down as ore, which kinda works. It does create the ore where it hits but ignores the amount field. It only creates a 50 quantity spot. I've been modding for all of 1 day so my mod fu is terribly weak.
