I like the idea, but I think some tweaks are needed.
Players will still have to search for other overworld veins, but by that time they will have better tools that can mine faster than flint.
Looking at other Overworld veins:
Also, be sure to read https://gtnh.miraheze.org/wiki/Ore_Generation especially the Efficient Mining section.
With the new oregen, there will be many less empty oreveins. Even so, I estimate 1% of players will need to search at least 56 centers to find casseterite sands for tin, so this tool will still be very useful for them.
Flying around some mountains, I could find a few small Copper ores here and there. I couldn't see any Tin ores, probably because they are really hard to see?
I think this tool could be very useful for players. Recommend adding some in village smithy and dungeon chests if it is added, along with adding tin/copper/iron dusts to the chests. Makes village raiding at tier 0/0.5 very viable strategy.
Mod is ready and i test it rn.
Can PM me a copy? I'd like to check it out. Are you going to use it as-is, where people have to find the ores first, or my suggestion that dusts gathered with small ores work as well?
Yes I can link it
i will try with dusts suggestion
Cool
Will test this week.
Okay, here are my comments after testing.
IFU-0.9.zip
@richardhendricks this this if you want to test it
dust suggestion is working
woble sound is added
@EnnekPL What will the license terms for the mod be? Will it be open source?
Wobble sound is perfect, nice and subtle, can be heard even when raining.
I could not get dusts to work, which did you try?
I was over brown limonite, tried brown limonite dust and iron dust.
Over cassiterite sand, tried cassiterite dust, cassiterite sand dust, tin dust.
Could only detect with actual ores.
Also, one other problem - tool does not detect GT ores until after they become blocks. By default they are tile entities and only turn into blocks when the object next to them updates. To demonstrate, place ore item into detector, then delete blocks using COFH commands (COFH clearblocks command does not do block update)
/cofh clearblocks
wait for blocks to delete then fly around with electronic prospector and compare against effect.

Visually:

After placing torch to force block update:

Also, I assume this is a client-side mod? So should not affect server TPS when in use?
Yes it will be open source mod so anybody can change anything.
How dust work
Thank you, that video is very helpful. So the one question to watch out is that GT ores start as tile entities, and are not populated until they are updated. So I think the orefinder will only work on the ores that are exposed to air? You can see my previous update with the pictures and COFH command to delete stone/dirt/etc.
for now I figure out what's hapen because once work correct other time as you present
Thank you for your contribution. We will be updating the mod to meet our needs.
Orefinder has been updated to work server-side to detect unexposed GT ores.
