Mineral Detector

[randomproof]

When placed the mineral detector scans all the blocks around it and gives you an indication of how much iron, coal and mese is found. The face of the detector will show colored dots if any is found and when you hove the cursor over the block it will tell you exact amounts.

UPDATE:
- Changed textures to remove compass style
- Added variable range (each time placed node is punched it will cycle through min and max ranges, 4 to 12 for now)

Updated for code changes March 2012

I like the mod!

[MrThebuilder3]

wow:)

[Gatharoth]

LOVE IT! This will help solve the rare iron problem XP All a person needs to do is get lucky and find 1 iron.

no, they have to find all the iron to make the iron blocks!

Yeah, wasn't paying too much attention to the materials needed ^^; I = failed

[randomproof]

I wanted to make this a non-trivial device to make so it takes a lot of iron to make (think of it as the casing and the electronics/magnetics inside) and a sample of each of the ores to be found.

Of course, I could add a version that doesn't use steel blocks and just make it have a smaller range?

[sapier]

what about making it smaler range and only supporting on specific ore?

[MrThebuilder3]

If you are downloading the compressed archive you need to change the directory it is in to "mineral_detector", take out the "randomproofs-minetest-mods-" part. I need to look in to renaming all of my mods to match the default created directory, but that will most likely have to wait until tomorrow.

[randomproof]

I've thought of that and I will do that tomorrow. I've been thinking about how much info to give the player. I could go so far as to say how many ore blocks are at each range. I don't think it is good to give to much, though.

ok thanks:)

[MrThebuilder3]

it works:D

[Calinou]

Wow, I like it.
You should add some confirmation message when changing its range, too (if not done already.)

[randomproof]

The infotext was changed to have the range listed first before the amounts are listed.

[randomproof]

Added coal detector, iron detector, and mese detector. Look in the init.lua file for the recipes.

I've got this message while trying to put detector on the ground.

My bad for not testing the way I should have.

I've uploaded the fix but here it is too:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.register_on_placenode(
function(pos, newnode, placer)
    if string.match(newnode.name, "mineral_detector:") ~= nil then
        local meta = minetest.env:get_meta(pos)
        meta:set_infotext("")

        if newnode.name == "mineral_detector:detector" then
            UpdateDetectorAll(pos, min_search_distance)
        elseif newnode.name == "mineral_detector:iron_detector" then
            UpdateDetectorIron(pos, min_search_distance)
        elseif newnode.name == "mineral_detector:coal_detector" then
            UpdateDetectorCoal(pos, min_search_distance)
        elseif newnode.name == "mineral_detector:mese_detector" then
            UpdateDetectorMese(pos, min_search_distance)
        end
    end
end
)


[hurufu]

Now it works :)

[hmmm]

I hate how ores don't touch each other. In minecraft, if I find one ore I've found all the ore in that small deposite of like 3-5 ore. In minetest, I have to dig blindly around the area I found the one ore and hope there's more ore there.

[sdzen]

it adds to the challenge after all this one is supposed to take survival multiplayer in a new direction

[randomproof]

Just pushed the update for the new code changes.

[kahrl]

I see in the diff that you use dug_item, which doesn't work anymore (I think?). The field is now called drop, e.g.
drop = 'mineral_detector:detector 1'
and so on.

Thank you. Now fixed.

i get the same thing aswel

[randomproof]

I pushed the update just now. The change is below if you don't want to pull it from git.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

...
minetest.register_on_punchnode(function(pos, node, puncher)
    if string.match(node.name, "mineral_detector:") ~= nil then
        if puncher:get_wielded_item():get_tool_digging_properties().dt_crumbliness ~= -1 then
            return
        end
...


[csbeav]

Thanks Randomproof,

I copied the text from your fix above and opened init.lua inside the ~/.minetest/usermods/mineral_detector directory, and pasted it at line 476 and forward. Now it works great. Great mod and hopefully we won't have to remove mountains to find the gold anymore. ;)

what is that brown lump and i have a weird tar.gz file!
