Custom Scenario Errors: Please Help!

[DarkSeahorse635]

I was inspired by a recent Friday Facts to create a custom scenario similar to the ones in the base game. In short, the player must secure the perimeter of a small pre-built base, find a train yard with an artillery turret and enough supplies to launch a rocket, and build a train line across the map to a launching silo and launch the turret to win. Unfortunately, I had no experience with c++ before opening up the control folders and the code is giving me a hard time.

Upon running the scenario, the error I get is "Error while running on_init: ...Data/Roaming/Factorio/temp/currently-playing/control.lua:6: attempt to index field '?' (a nil value)"

I'm aware that the problem is with the arguments for "on_init", but I cant find the "currently-playing" folder in "Roaming/Factorio/temp" so I don't know how the function works. Please Help! thanks in advance!!

Notes: I used map editor to build the map and the base. I used the "tag" feature to tag entities that I wanted to fill with items at the start of the game.
ldswagon = low density structure wagon
rcu = rocket control unit
rf = rocket fuel

The control folder should be below. Let me know if anything else is needed.

this Data/Roaming/Factorio/temp/currently-playing/ can be found when you play the game and it not crashing to desktop but its not important because your scenario is faulty.

Could you elaborate on "faulty"? Is it something wrong with story_table or under script.on_init?

As per the error "control.lua:6" Look at line 6 of control.lua:

Code: Select all

game.players[1].force.disable_all_prototypes()

"players" isn't a property of "game", you're looking for "player" so when you try to index "players" it's throwing an error.

Code: Select all

  game.player[1].force.disable_all_prototypes()
  game.player[1].force.clear_chart()

Wtf are you talking about...? game.player is only available in the console, game.players is the list of players. The issue is that on_init no player exists because it hasnt been created yet. OP could access the force directly instead, using game.forces.player.disable_all_prototypes() etc.

Ah. Don't mind me then ^^ too early to be trying lol

I'm having trouble actually creating this character. If no player exists, the recipe/technology/character inventory lists won't work because there is no player to index. I used the code from the campaigns to write that part which accomplishes this task with no issue. How do the campaigns create a character?
