1. ## Drone Pathfinding?

Depends on the size of the known area. At a distance of 1-2 chunks, A* or JPS work quite well even on a 1 tier CPU. A* requires a lot more memory, but its heuristics are better for drones.
2. ## miner Robot-miner with geolyzer

I own black magic. Сan determine the block hardness in one scan, at any distance. Maybe I'll write a post explaining how to do it.
3. ## Scientific approach to Geolyzer

I know an easy way to find out the hardness of a block at any distance in one scan. Accuracy 99.31% When move the robot a couple of blocks, the accuracy will be 100%.
4. ## Clock - displays ingame time

Yes, this program is outdated. here is fixed https://pastebin.com/eZkdDK7N
5. ## unrecoverable error prank

That is mighty easy. computer.pullSignal = nil
6. ## mining [Subproject] Mining Robot with Geolyzer

local function compass() local sides = {2, 1, 3, 0} -- links of cardinal points, for raw data local D = nil for s = 1, #sides do if robot.detect(3) or robot.place(3) then -- check for block in front side local A = geolyzer.scan(-1, -1, 0, 3, 3, 1) -- scan blocks around the robot robot.swing(3) local B = geolyzer.scan(-1, -1, 0, 3, 3, 1) for n = 2, 8, 2 do if math.ceil(B[n])-math.ceil(A[n])<0 then -- check the difference between two scans D = sides[n/2] -- set the direction break end end else -- turn if there is no block robot.turn(true) end end return D -- return the direction end local min, max = 2.2, 40 -- minimum hardness selected to capture lead ore from IC2 local border = nil local X, Y, Z = 0, 0, 0 local function scan(xx, zz) -- 8x8 block scan local raw, index = geolyzer.scan(xx, zz, -1, 8, 8, 1), 1 for z = zz, zz+7 do for x = xx, xx+7 do if raw[index] >= min and raw[index] <= max then -- add ore coordinates to list -- coords of the geolyzer will be converted to local coords of robot table.insert(WORLD.x, X+x) table.insert(WORLD.y, Y-1) table.insert(WORLD.z, Z+z) elseif raw[index] < -0.31 then -- if a block with a negative hardness is detected, set the flag to end scanning border = Y end index = index + 1 end end end local quads = {{-7, -7}, {-7, 1}, {1, -7}, {1, 1}} while not border do if robot.move(0) then Y = Y - 1 end for q = 1, 4 do scan(table.unpack(quads[q])) end end
7. ## mining [Subproject] Mining Robot with Geolyzer

Robot can determine the facing using the geolizer. And you can scan 16x16 blocks at a time, as I did.
8. ## gps GPS on microcontrollers

Program and library for building GPS network. https://github.com/DOOBW/OC-GPS Download: wget https://raw.githubusercontent.com/DOOBW/OC-GPS/master/usr/bin/gps.lua /bin/gps.lua wget https://raw.githubusercontent.com/DOOBW/OC-GPS/master/usr/lib/gps.lua /lib/gps.lua The functionality is the same as in the ComputerCraft. Additional command "flash" allows to upload firmware to EEPROM. When the coordinates are precisely determined, when flashing the position of the microcontroller can be omitted - at the first start it will determine its position from neighboring satellites and save on EEPROM. GPS network startup example.
9. ## miner Robot-miner with geolyzer

Update Added ability to work with solar panels. When the energy level falls below 30 percent, the robot climbs to the surface and charges from the built-in solar panel. There is a check of time of day and weather conditions.

11. ## Is there video games for OC?

There are quite a few games, but their do not post them on this forum. For example: simple RPG Or flappy bird
12. ## miner Robot-miner with geolyzer

I fixed it. Download the file again, please. The error was due to the computer.beep(), which is not compatible with the old versions OpenComputers. P. S. Instead of batteries, I advise you to use the experience upgrade or additional generator
13. ## How to get dimension of player with debug card

Such objects are just tables, they must be processed in the correct sequence. players = component.debug.getPlayers() -- get a players list for i = 1, players.n do print(players[i]) -- display the name of the next player end player = component.debug.getPlayer(players[1]) -- get player proxy by name from list world = player.getWorld() -- get the proxy of the world in which the player is located print(world.getDimensionName()) -- print the name of the world -- Or you can get everything at once players = component.debug.getPlayers() for i = 1, players.n do print(players[i], component.debug.getPlayer(players[i]).getWorld().getDimensionName()) end
14. ## miner Robot-miner with geolyzer

There are variables in the code that can be customized chunks - how many chunks need to be processed min and max - the minimum and maximum hardness of mined blocks port - port for interaction with the robot (if a wireless card is installed)
