Hi,

The api clearly say that on_preplayer_mined_item fire when the player start mining something

"Called when the player starts mining something"
http://lua-api.factorio.com/latest/even ... mined_item

Yet it actually fire on the same tick # as on_preplayer_mined_item, right before the entity is deleted.

so it's goes like this
- item start being mined
- mining progress bar reach 100%
- [...]
- tick begin
- [...]
- on_preplayer_mined_item is fired with the entity as a parameter
- entity is removed from the memory by the c++ logic.
- on_player_mined_item is fired with the result item_stack as a parameter
- [...]
- tick end
- [...]

Is this a bug or really a very niche case event with a wrong description? if it's not a bug can we get a proper event that fire when the player start mining something so we can do stuff like setting entity.minable to false and stop the mining. Or maybe remove the mining-tool from the tool_inventory. Something like that.

forum post where I'm describing what i'm trying to achieve -> viewtopic.php?f=25&t=31853

Thanks!

The docs are just wrong.

As for your other comments: just set the entity to not minable to begin with if the player shouldn't be able to mine it.

But I wan't those entity to be mineable, just not by that particular mining-tool

Then use the hardness property of entities and mining tools. You can set it up so a give entity isn't minable by a given tool but other tools can mine it.

oh nice, completely missed that, thanks!

so it's the damage that the mining-tool deal that decide what hardness it can mine?? how does the math work?

it's not the damage, and there really nothing else in the doc about hardness or how it work beside setting a ressources hardness.. so what am I looking for??

Fixed the documentation for 0.14.2.
Any entity can have "minable" property, which is table that can contain: mining_time, result/results, mining_particle, mining_trigger and hardness
Mining tool has property speed.
As I understand it, mining progress is multiplied by (speed - hardness), and if speed < hardness you won't be able to mine the entity.

Moved to Modding help.

ah too bad that mean I can't use this for what I'm trying to achieve since what I want is a high speed mining tool that can only mine wood.

anyway, thx for updating the doc about this.
