OnSpawningEntity

[tonibm19]

I'm trying to make a plugin that makes sure mobs spawn in the right biome.
Here's the code.

Code:

function OnSpawningEntity(World, Entity)
    if (Entity:GetClass() == "wolf" and World:GetBiomeAt(Entity:GetPosX(),Entity:GetPosZ()) ~= 4) then  
        Entity:Destroy()
    end
end

It don't works, wolves spawn everywhere.
I don't get any error in console

try some debugging like use

print(Entity:GetClass())

to see what it returns etc.

Are there named constants for biomes? If so, you should use them.

Also, wolves can spawn in tundra and forest AFAIK.

I tried with this:

Code:

function OnSpawningEntity(World, Entity)
    print(Entity:GetClass())
    if (Entity:GetClass() == "cWolf" and World:GetBiomeAt(Entity:GetPosX(),Entity:GetPosZ()) ~= 4)then
        print(Entity:GetClass().." spawning on "..World:GetBiomeAt(Entity:GetPosX(),Entity:GetPosZ()))
        Entity:Destroy()
    end
end

All works except destroy the entity. I'll try with OnSpawnedEntity, because if entity is not spawned, you can't destroy it

Now it work, but when entity is destroyed, you see it, and can't interact with it. It seems entity is removed from server but not from client.
Code:

Code:

function OnSpawnedEntity(World, Entity)
    print(Entity:GetClass())
    if (Entity:GetClass() == "cWolf" and World:GetBiomeAt(Entity:GetPosX(),Entity:GetPosZ()) ~= 4)then
        print(Entity:GetClass().." spawning on "..World:GetBiomeAt(Entity:GetPosX(),Entity:GetPosZ()))
        Entity:Destroy()
    end
end

Use the OnSpawningEntity() hook and return true if you don't want the entity to spawn.
Also, as Bearbin said, use named constants for biomes: biForest, biTundra etc. Here's a list:

biOcean            = 0,
biPlains           = 1,
biDesert           = 2,
biExtremeHills     = 3,
biForest           = 4,
biTaiga            = 5,
biSwampland        = 6,
biRiver            = 7,
biHell             = 8,  // same as Nether
biNether           = 8,
biSky              = 9,
biFrozenOcean      = 10,
biFrozenRiver      = 11,
biIcePlains        = 12,
biTundra           = 12,  // same as Ice Plains
biIceMountains     = 13,
biMushroomIsland   = 14,
biMushroomShore    = 15,
biBeach            = 16,
biDesertHills      = 17,
biForestHills      = 18,
biTaigaHills       = 19,
biExtremeHillsEdge = 20,
biJungle           = 21,
biJungleHills      = 22,

But with OnSpawningEntity the entity hasn't spawned yet so he could not get the coords with the cEntity:GetPos() functions.

[bearbin]

It seemed to work in his examples above.

The entity hasn't spawned, but its coords should already be valid. The hook is supposed to make that available, so that plugins may nudge the entity a bit.
