I am currently working on the Fireballs mod, and I am trying to get it so that it can damage mobs from the Simple Mobs mod, and I need some help. |
| 16:18 |
ExcaliburZero |
The GitHub repo for the mod is here: https://github.com/rocketslime11/fireballs |
| 16:19 |
ExcaliburZero |
I think I understand how to damage a mob, but I don't know how to find mobs who are in the blast radius of the fireball. |
| 16:20 |
ExcaliburZero |
In the fireball code there is code to check for players, but I do not know how to do the same for entities. Can someone help me with this? |

ExcaliburZero: Just remve the is_player check from the minetest.get_objects_in_radius() loop. |
| 16:57 |
ExcaliburZero |
Thanks! I'll try that. |
| 16:59 |
ExcaliburZero |
I tried that and when I attacka mob it gave me an error. |
| 17:00 |
ExcaliburZero |
ERROR: ServerError: LuaError: ...pminetest-0.4.8bin..modsfireballs/thunder sword.lua:59: attempt to index local |

ShadowNinja |
That's not the full error message. And you can't call methods like get_look_dir on non-player objects. You have to use set_hp(get_hp() - 5). |
| 17:09 |
ShadowNinja |
(Or something similar) |

Can you show me what that would look like in the code? I'm not very fimilliar with coding. |
| 18:16 |
ExcaliburZero |
When I put it in I got this error: http://codepad.org/Ud9UcwHR |
| 18:33 |
ShadowNinja |
object:set_hp(object:get_hp() - X) Where X is the amount of damage. |
| 18:34 |
ShadowNinja |
You should probably wrap that in math.max to make sure that you don't set a negative HP. |
| 18:34 |
ShadowNinja |
object:set_hp(math.max(0, object:get_hp() - X)) |
| 18:40 |
ExcaliburZero |
I tried that, with decailiring the variable object with the value of the variable player and I got another error. |

ExcaliburZero: You can't get the look direction of non-player objects. |
| 18:49 |
ShadowNinja |
Add hit_object or the like. And make it a global inside a namespace so it isn't copied in half a dozen files. |
| 18:56 |
ExcaliburZero |
I am trying that, but it gives me an error: http://codepad.org/KLOEQ1Kw |
| 18:57 |
ExcaliburZero |
The current code is: http://codepad.org/c7t5L0wg |

ExcaliburZero: Um, object:set_hp doesn't return anything. |
| 19:55 |
ShadowNinja |
And you use player:get_pos() instead of object:get_pos() |
| 19:56 |
ShadowNinja |
Remove the punching and return value and fix ^ and it should work. |
| 20:06 |
ExcaliburZero |
I tried that and it gave me an error. |

Here is the current code: http://codepad.org/gy6jPoqy |
| 20:12 |
ShadowNinja |
... Look at your code. |
| 20:13 |
ShadowNinja |
The object is named player, and you get it's position three times, then generate a vector based on the difference of the objects position, which will alvays be 0. |
| 20:14 |
ShadowNinja |
You should use vector.subtract(s, p) BTW. |
| 20:14 |
ShadowNinja |
(If that made any sense) |
| 20:16 |
ShadowNinja |
You also spawn fire near the player rather than around the actual position of the explosion, and you use a 2x2x2 cube aligned to the +* axis, and a 3x3x3 cube later. |
| 20:25 |
ExcaliburZero |
Sorry, I don't fully understand what you are saying. I adapted the code from PilzAdam's fireball code from the Dungeon Master mob, so I don't have a total understanding of how it works. |
| 20:28 |
ShadowNinja |
ExcaliburZero: Read http://www.lua.org/pil/contents.html |
| 20:38 |
ExcaliburZero |
I've read a bit of that guide. However I tend to not be able to learn coding well from just reading. I tend to learn it easier by modifying code to see how it works, using it, and then learn exactly what it does. |
| 20:39 |
ExcaliburZero |
What exactly is causing the error? |
| 20:41 |
ExcaliburZero |
I think I understand (to a degree) what you are saying. Here is the modified code: http://codepad.org/eJUuctnn |
| 20:43 |
ShadowNinja |
It failed because the method is called getpos(), and vec is unused. |
| 20:45 |
ExcaliburZero |
So Ineed to remove the vec variable and what do I change the "player:getpos()" to? |
| 20:47 |
ShadowNinja |
object:getpos(). And change player to object everywhere but in hit_player. |
| 20:51 |
ExcaliburZero |
The code is now: http://codepad.org/jgr2MXt5 |
| 20:52 |
ExcaliburZero |
It doesn't throw any errors, however when the item is used the ball hits the player and explodes, as opposed to being sent in the specified direction. |
| 20:56 |
ShadowNinja |
Prevent it from exploding in the first second or so, or spawn it farther away. |
| 20:56 |
ExcaliburZero |
Why is it just doing this now? It didn't before. |
| 20:58 |
ShadowNinja |
Because it doesn't crash now? :-D |
| 20:58 |
ShadowNinja |
You might have spawned it farther, or if a DM spawned it would have ignored him. |
| 20:58 |
ExcaliburZero |
I mean it didn't act like this before I tried modifying the code. It was working before I tried modifiying it today. |
| 20:59 |
ExcaliburZero |
From my understanding of it, it would spawn the ball about 1 or so nodes above the player, but I'd guess it is now spawning it on the player for some reason. |
| 21:03 |
ExcaliburZero |
I'll try testing increasing the spawning height. |
| 21:04 |
ExcaliburZero |
The problem appears to be that it is spawning then immediately exploding. |
| 21:09 |
ExcaliburZero |
Ok, I'll put in some print statements to see what exactly it is doing. |
| 21:12 |
ExcaliburZero |
It seems that I need to find a way to get it to use something like "is_player()" but for entities. |
| 21:12 |
ExcaliburZero |
Do you know how to do that? |
| 21:15 |
ShadowNinja |
entitt.object:is_player() |
| 21:15 |
ShadowNinja |
entity* |
| 21:17 |
ExcaliburZero |
So that will determine if it is an entity? |
| 21:18 |
ExcaliburZero |
I tried that and it threw an error. |
| 21:18 |
ShadowNinja |
Thet will determine if the enity belongs to a player object. |
| 21:18 |
ExcaliburZero |
I meant, something that will determine if it is an entity, just like "is_player()" determines if it is a player. |
| 21:19 |
ExcaliburZero |
Is there something like that? |
| 21:33 |
ShadowNinja |
No, although you could check if it was a table with a object field. |
| 21:34 |
ExcaliburZero |
How would I do that? |
| 21:40 |
ExcaliburZero |
Here is what I have right now:http://codepad.org/JulIilMi |
