Tutorial problem

[matjojo]

So I was just trying to get into modding, when whilst doing the tutorial(link on bottom) I ran into this error:

Code: Select all

Error while loading entity prototype "bomber" (car): no such node (energy_per_hit_point) modifications: BomberTutorial

At first I went through the base game files seeking for the car entity to seek for what the node energy_per_hit_point would be. when This didn't work out (I couldn't find the car) I tried seeking on the forum. i came across one post kinda helping. But what he said would not work on the tutorial, beacuse he talked about adding it above the "light node", but that one I also don't have.
So here I am, with the question: Where should the node in question be added?(on what line.) And, what does this node do?

You can find the prototype for the vanilla car in data\base\prototypes\entity\entities.lua starting from line 797.

Code: Select all

{
    type = "car",
    name = "car",
    icon = "__base__/graphics/icons/car.png",
    flags = {"pushable", "placeable-neutral", "player-creation", "placeable-off-grid"},
    minable = {mining_time = 1, result = "car"},
    max_health = 200,
    corpse = "medium-remnants",
    dying_explosion = "huge-explosion",
    energy_per_hit_point = 1,
    resistances =
[...]

I'm guessing that energy_per_hit_point was later added (0.11.18?) according to https://github.com/Dysoch/DyTech/issues/292
and is required for the car entity to load.
So just add that line somewhere in the car definition of your mod (the entity.lua file in step 4 of the tutorial).
The order of the nodes doesn't really matter, in this case adding it after the corpse node (line 805) should be fine.

I can't tell for sure (haven't tried it) but I think this node changes the amount of damage done when the car/tank/... crashes into other buildings.

As of my understanding, entities, items, and other data definition are simple LUA table, and in that case associative array: we use string names as keys (e.g. {name = 'bomber'}).

Which means that as long as you use the right name at the right level (e.g. not in a sub array if it's an entity's prime attribute) it should be just fine.

Whichever the position you would still access the name property by its name like so:

Code: Select all

entity.name

Someone correct me if I'm wrong (still learning lua but doesn't sound so different from other languages at this level.

thanks, I wasn't really sure as to where to add it, but as you said, the order does not matter. thanks!
