Disable placement of specific structures

[Tami]

Is it possible to disable placement of structures like laser towers without preventing laser tower tech or turrets?
Same goes for solar panels.

Same goes for solar panels.

During prototype/data stage or during runtime?

Example with /permissions settings.
Would be great to disable placement of certain structures.
If not possible with permissions (as it is yet), maybe a simble lua command script could help too if there is one. Keep in mind that the laser turrets needs to be build for certain receipe, but not be placed, same for solar for certain receipes.

You will have to listen to on_built_event, something like this:

Code: Select all

script.on_event(defines.events.on_built_entity, function(event)
  
  local entity = event.created_entity
  local player = game.players[event.player_index]
  
  if entity.name == "laser-turret" then
    entity.destroy()
    player.insert{name = "laser-turret", count = 1}
    player.print("Placing laser turrets is not allowed")
    return
  end
  
  if entity.name == "entity-ghost" and entity.ghost_name == "laser-turret" then
    entity.destroy()
    player.print("Don't build ghosts or blueprints of laser turrets either.")
    return
  end
  
end)

Thank you very much

From where do we listen ? Is this accomplished with your syntax contained within Control.lua in the Entities folder, or somewhere else ?

I'm new to modding, and trying to remove the module slots from assembling-machine-2 and add pipe/fluid input to the assembling-machine (grey one).

EDIT !! - I meant to say that I am trying to prevent the placement of solar panels and accumulators as structures... since that's related to this thread here/// but I am also trying to change the assembling machines too !!


p.s. perhaps I will post this in a new forum thread, but I did want to reply here since it seems like an open question .

thanks
Jason

Urgs, entity.destroy() will destroy the entity so the entity is lost. It should be returned to the player.

I think a better solution to preventing placing entites, at least when you want to do it for all players for the whole game, is to simply remove the place_result property from the item:

Yea that sounds good, as I didn't even look into the result of this code. I have been too preoccupied with the original issue. Where do we put this code ?
In other words, which folder location, and which filename ?

Control.lua ? Entities.lua ? in the root directory ? in the scripts folder ?

data.lua up to data-final-fixes.lua

This is changing the prototype. Nothing runtime and can't be changed at runtime.

I have more questions than answers but:
If you want to prevent the placement in order to maintain status for an achievement, then it is probably too late to catch it after it has been placed and remove it. I am not sure, but that would be my guess.

Again I am not sure, entity flags include "placeable-player" which seems to mean the player is allowed or able to place the entity... you can probably remove that flag or something
I do not know if that will prevent bots from placing one on a ghosted blueprint either but would like to find out

Easy enough to test yourself or read up on the definition of the flag.
