00:06 ExcaliburZero I tried the code, but the fireball, when placed, doesn't move. Here is the current code: http://codepad.org/wzZb6Hrt
00:10 ExcaliburZero From what I can guess, from seeing the results, the entity of the fireball is placed, but it doesn't move.
00:13 PilzAdam      "minetest.env:add_entity(pointed_thing.above, "neoblocks:fireball")" returns on object ref
00:14 PilzAdam      you have to call the setvelocity() function of that objec ref
00:15 ExcaliburZero Where and how do I do that?
00:22 ExcaliburZero I think I may have figured it out. I'll try it out now.
00:26 PilzAdam      something like: local obj = minetest.env:add_entity(pointed_thing.above, "neoblocks:fireball")
00:27 ExcaliburZero When I placed the fireball item it gave me an error. The code is here: http://codepad.org/X1BRZjkx
00:27 PilzAdam      and then obj:setvelocity({x=1,y=0,z=1})
00:27 ExcaliburZero "ServerError: LuaError: error: ...st-0.4.6\bin\..\mods\minetest\neoblocks\fireball.lua:54: attempt to index global 'p' (a nil value)"
00:27 PilzAdam      yea, p and s are defined there
00:28 PilzAdam      make something like: local dir = placer:get_look_dir(); local vec = {x=dir.x*3,...}
00:28 PilzAdam      ... means do it for y and z too
00:28 PilzAdam      <-- too lazy to type it out ;-)
00:29 ExcaliburZero Ok, I'll try that.
00:32 ExcaliburZero It now gave me "ServerError: LuaError: error: ...st-0.4.6\bin\..\mods\minetest\neoblocks\fireball.lua:56: attempt to index global 'obj' (a nil value)"
00:32 ExcaliburZero Code: http://codepad.org/Zn87U3op
00:33 PilzAdam      put an "local obj =" in front of the add_entity() call
00:34 ExcaliburZero So, "local obj = "neoblocks:fireball"," ?
00:34 PilzAdam      nope
00:34 PilzAdam      local obj = minetest.env:add_entity(pointed_thing.above, "neoblocks:fireball")
00:35 ExcaliburZero Ok, I'll try that.
00:38 ExcaliburZero It now moves, but it won't explode on impact.
00:39 PilzAdam      thats because you are missing the on_step() function like its used in api.lua
00:39 PilzAdam      that is the function that triggeres the hit_player() and hit_node() functions
00:42 ExcaliburZero Like this? http://codepad.org/WiegzjjZ
00:44 PilzAdam      seems good
00:45 ExcaliburZero I'll test it out.
00:48 ExcaliburZero Ok, I ran into one of the already placed fireballs, and got an error.
00:48 PilzAdam      sorry, I got to sleep
00:48 PilzAdam      its way to late already
00:49 ExcaliburZero Ok. I'll probably be back here tomorrow.
20:53 ExcaliburZero I am currently working on a code for a fireball attack that is modified from Simple Mobs, and the fireball currently moves, but doesn't impact. Can someone help me with it
20:53 ExcaliburZero The code is here: http://codepad.org/gZBrZV7v
20:58 ExcaliburZero Scratch that, it is currently not working, it gives me an error.
21:00 ExcaliburZero ServerError: LuaError: error running function 'on_step': ...st-0.4.6\bin\..\mods\minetest\neoblocks/fireball.lua:24: attempt to call method 'getpos' (a nil value)
21:00 thexyz        what's the error?
21:00 ExcaliburZero The current code is here: http://codepad.org/ceRvy5d8
21:01 thexyz        it should be hit_player = function(self, player)
21:02 ExcaliburZero I'll try that.
21:05 ExcaliburZero The fireballs now explode, however the fireball item doesn't summon fireballs anymore, since I switched it to "on_use".
21:09 ExcaliburZero Wait, I may have fixed the problem.
21:14 ExcaliburZero Nope, now it still won't create fireballs unless aimed at a block.
21:15 ExcaliburZero This is the current code: http://codepad.org/dMW8vHuL
21:15 PilzAdam      on_use is only called when pointing at a node or object
21:16 ExcaliburZero How can it be called on a normal click?
21:16 PilzAdam      ehm, wait, on_place is only called when pointing at a node; on_use is always called
21:17 PilzAdam      pointed_thing.above only exists if you point at a node
21:17 ExcaliburZero What should I replace it with?
21:18 PilzAdam      use something like playerpos + (0,2,0) + dir
21:18 PilzAdam      as spawn pos for the object
21:20 ExcaliburZero Here is what I currently have: http://codepad.org/a5s8ozTC
21:20 ExcaliburZero But it won't load.
21:20 PilzAdam      ehm,
21:21 PilzAdam      you have to add the coordinates per axis, like: {x=playerpos.x+0+dir.x,...}
21:21 ExcaliburZero Ok.
21:22 PilzAdam      (0,2,0) is just a short way to write a vector
21:22 PilzAdam      in lua that is {x=0,y=2,z=0}
21:25 ExcaliburZero I made the changes to the code, it is now here: http://codepad.org/Elgp09ec
21:26 ExcaliburZero However it only spawns a fireball when pointed at a node, and gives an error.
21:26 PilzAdam      remove the "if pointed_thing.above then" and define playerpos
21:27 ExcaliburZero ServerError: LuaError: error : ...st-0.4.6\bin\..\mods\minetest\neoblocks/fireball.lua:69: attempt to index global 'playerpos' (a nil value)
21:28 PilzAdam      something like: local playerpos = placer:getpos()
21:28 ExcaliburZero Ok, I'll try that.
21:31 ExcaliburZero It works!
21:31 ExcaliburZero Thanks!
21:32 PilzAdam      I suggest you to read some basic programming tutorial
21:33 ExcaliburZero Do you know where some good ones for lua are?
21:34 PilzAdam      it doesnt have to be a Lua tutorial
21:34 PilzAdam      any programming language would work to get some basic idea about programming
21:35 ExcaliburZero I already know some basic Java, and Javascript, as well as a large amount of wikitext.
21:35 ExcaliburZero So what language would be good to learn that would transfer to lua well?
21:36 PilzAdam      well, Lua is a scripting language
21:36 PilzAdam      so you could choose another scripting language like Javascript
21:37 PilzAdam      although I learned Lua without knowing other scripting languages well before
