Lua HUD

[ghost]

No description provided.

[kaeza]

Some documentation would be nice.
Do you have any mod to test this?

[PilzAdam]

Yea, description is definetly needed here.
This requires a protocol version bump and why are you deleting a commen in camera.cpp that is completly unrelated to your changes?

[ghost]

Well, I used this to test the hud out:

minetest.register_craftitem("test:test", {
    inventory_image = "default_tool_steelaxe.png",
    on_place = function(itemstack, placer, pointer)
    local id1 = placer:hud_add(id1,
        {type="I", text="default_tool_steelaxe.png",
        position={x=0.5, y=0.5}, scale={x=5, y=5}})
    local id2 = placer:hud_add(id2, {type="T", text="HELLO!",
        scale={x=100, y=100}, position={x=0.5, y=0.25}})
    local id3 = placer:hud_lock_next_bar()
    placer:hud_change(id3, 3, "default_tool_steelaxe.png")
    placer:hud_change(id3, 4, 5)
    local id4 = placer:hud_add(id4, {type="i", text="main", number=5, item=2,
        dir=2, position={x=0.25, y=0.5}})
        minetest.after(1, function()
            dump2(placer:hud_get(id1))
            placer:hud_unlock_bar(id3)
            placer:hud_rm(id1)
            placer:hud_rm(id2)
            placer:hud_rm(id3)
            placer:hud_rm(id4)
        end)
        return itemstack
    end,
})

For documentation, the players now have two extra methods: hud_add and hud_rm. The first arg of both of these is a string for identification. hud_add's second arg specifies the "drawform", a simple string specifying the type and specs of an object on the screen. Examples can be seen in above.
EDIT: updated code.

Can you add documentation to doc/lua-api.txt?

[Zeg9]

👍 This would be really great (if it works, haven't tested, but I guess it does)

There's a typo on the third changed line - "completely". You might want to squash the commits too.

Having Lua HUDs is pretty awesome, I can see a ton of potential uses for it.

[PilzAdam]

"but have a comletely different syntax. This may be changed later on."
This isnt good at all.

[ghost]

Arrrg. Pirates are baad spelllers. :)

Anyway, if you like, I can rewrite the code to use the formspec syntax.

[Zeg9]

I think you can keep this one, but don't say "it might be changed later"... Wait for PilzAdam's answer though ;)

[PilzAdam]

This comes rather out of the blue. We havent discussed it at the IRC or anything else.
I think it would be best if you come to #minetest-dev @ Freenode and discuss the syntax and other stuff with the other core devs.

[ghost]

+1 hope it gets added

[iqualfragile]

Please make sure to have some kind of mechanism handling minetests possibilities: having a lot of mods.
You need to provide some way to check if the region one wants to draw in is already occupied by another mod, or even better: do not allow positioning of certain elements from lua (esp. the statbar) but position it automatic.
If no such mechanism gets added minetest will look like a website from the nineties+ a lot of banners within no time so i would be strongly against merging it.

I'm adding this feature, but only so far for statbars. Maybe more will come soon.

Moreover, this would prevent you from overlaying, e.g. some text over an image. A real estate request feature would be nice, but it would not be automatic.
