Blocking Certain Mobs from spawning on certain blocks

How would I go about blocking certain mobs from spawning on a particular block.

i.e Zombies couldn't spawn on sand no matter the light level

 

Have you tried any code yet? People are much more likely to help, or should be, if you've shown you've at least given it some effort

 

Like drtshock said, you'll want to show some effort. Although, if you're lost, try looking into events first. Mostly, CreatureSpawnEvent.

Also, seeing as how you're having problem with this shows me you don't know much about Java or the Bukkit API, I'd suggest you read this tutorial before diving into this.

> getLocation() , find block under that location
> find the block based on that location
> do your check if that block is allowed to have that specific mob on

This only works for mobs that spawn on blocks. Withers, Dragons, Bats, and maybe other mobs do not spawn on a block but rather in the air so you can't really change that.

 

@NinjaWAffles @drtshock, i get what your saying, i've never done anything to do with creature spawning before so i don't even know where to start. Ive been making plugins for about 6 months now, but they've all been revolving around EventListeners and Schedules, i've never touched the manipulating entities side of things. So im not a noob i just don't have a wide range of knowledge.

 

This however is an EventListener, so you shouldn't have any trouble.

Some tips-
Use a CreatureSpawnEvent
Get the relative upwards face of the block 1 down from where the mob spawns. If this block face is recognized as sand, then you can set the event as cancelled.
You can use if statements to choose which mobs can spawn on the sand and which ones cant.

If you have any questions just ask

 

Thx @Milkywayz, ill give it a shot
