What's the radius where enemy structures block building?

It's not possible to build something near a military structure of an enemy force (e.g. radars, turrets, spawners). It seems the radius where enemy military structures block building is 50 tiles. Is that indeed a hard-coded value, or could it be changed?
Use case:
I want to place invisible, indestructible entities even if that was near an enemy military structure. To circumvent the block, I'd first check if I can place the entity; if not, I'd get the force of the first entity returned by
Code: Select all
surface.find_entities_filtered{
position = position,
radius = 50,
type = {"ammo-turret", "artillery-turret", "electric-turret", "fluid-turret", "turret", "radar", "unit-spawner"}
}
and use
Code: Select all
new_entity = surface.create_entity({
name = entity_name,
position = position,
force = enemy_force_name,
})
if new_entity then
new_entity.force = final_force_name
new_entity.destructible = false
end
to build it. But this would only work with the correct radius. (In multiplayer games with at least two enemy forces there may be situations where the entity still couldn't be placed. The workaround for that is suggestion: Don't tell the players an entity
will be placed, but that there's a chance -- with an adjustable probability of 0<p<1 -- it
could be placed.)

Thats not true, are you using some other mod that is doing that behavior? Just as AAI industries?

Indeed, I've used some mods active for testing compatibility. There are your own companion/kombat/mining/transport drones, the
updated construction drones mod, an alien-loot mod, AAI Programmable vehicles, and Creative mod that could be relevant.

That's a feature of AAI Programmable vehicles, as Klonan said. You can take a look at the mod code, aai-programmable-vehicles_0.7.14.zip\aai-programmable-vehicles\scripts\deadzone.lua. Easiest work around is probably to always place the entity as one of the ignored forces and then just change the force of the entity, since force changing doesn't raise any events. Or don't raise the script built event :p

Found it. There's even a runtime-global setting "Deathzone construction denial range", set to 50 tiles, just like the value I've measured.

OK, I thought of using the procedure sketched in my first post iff AAI was active, but your solution really is way easier! Other mods really don't need to know about the invisible entity, so not raising the event should work.
Thanks to Klonan and you for setting me on the right path!
