LuaGuiElement{type="camera",entity=<follow this>}

[eradicator]

Aummary

A method to make camera guis automatically follow an entity.

Description

I've looked all through the API doc and through several mods, and it seems that currently the only method is on_tick? Which feels clunky for such a simple task.

What for?

Picture-in-Picture viewing of players, robots, biters, etcpp.

+1. Also for type = "minimap", which is how base game train GUI works.

You can write the entity to follow after creating the element

Oh wow, thanks! I see for 'entity-preview' it says "The entity has to be set after the GUI element is created.", so maybe there's a technical reason why it can't be set in .add{} .

I added a note hinting at this functionality to the docs for the next release.

Yea, something like, the creation is wrapped with propertyTree into creationParameters (Basically internal Lua format), which can't wrap an Entity* pointer,
But setting it afterwards, we can just pass the Entity* pointer right into the CustomCamera

Using flib.gui-beta, I can just do

Code: Select all

{type = "camera", position = spidertron.position, surface_index = spidertron.surface.index, elem_mods = {entity = spidertron}},
