Following code only spawns a pig.

EntityRegistry.registerModEntity(RobotHelper.class, "robotHelper", 0, this, 64, 1, true);
EntityRegistry.registerEgg(RobotHelper.class, mainColor, subColor);

 

 

Following code spawns the entity but everytime i load the world from save the entity loads, stays there for 5 sec, then vanish, saving the map loading it again the entity again show up for 5 sec then vanish.

I'm overriding canDespawn and return false, i also tried setting enablePersistence() and forcing age to 0.

 

int i =EntityRegistry.instance().findGlobalUniqueEntityId();
EntityRegistry.registerGlobalEntityID(RobotHelper.class,"robotHelper",i);
        EntityRegistry.registerModEntity(RobotHelper.class, "robotHelper", i, this, 64, 1, true);
EntityRegistry.registerEgg(RobotHelper.class, mainColor, subColor);

 

 

Im sure im the one doing something wrong here, but im clueless at this point to why it is vanishing.

Walking around in the room after they vanish i realized im bumping in to them and suddenly 1 became visible, it seems this is a server->client sync issue

Are you only spawning them through the egg, or are you spawning them in your code somewhere?

tried both egg and world.spawnentity

Could you post your RobotHelper class?

Nothing in there really just part of the villager class

Following code only spawns a pig.

EntityRegistry.registerModEntity(RobotHelper.class, "robotHelper", 0, this, 64, 1, true);
EntityRegistry.registerEgg(RobotHelper.class, mainColor, subColor);

 

 

Following code spawns the entity but everytime i load the world from save the entity loads, stays there for 5 sec, then vanish, saving the map loading it again the entity again show up for 5 sec then vanish.

I'm overriding canDespawn and return false, i also tried setting enablePersistence() and forcing age to 0.

 

int i =EntityRegistry.instance().findGlobalUniqueEntityId();
EntityRegistry.registerGlobalEntityID(RobotHelper.class,"robotHelper",i);
        EntityRegistry.registerModEntity(RobotHelper.class, "robotHelper", i, this, 64, 1, true);
EntityRegistry.registerEgg(RobotHelper.class, mainColor, subColor);

 

 

Im sure im the one doing something wrong here, but im clueless at this point to why it is vanishing.

 

Same thing is happening to me. I have yet to figure out a solution.

Should add everything works fine until u save and reload the map, if you stay in the game after spawning a entity it stays visible, only when loading the map it vanishes. but you can still get pushed around by it, and collide with it, pushing it into a chest made it become visible, might be random

Stop using registerGlobalEntityID

im not using globalID, egg dont work without it, but i spawn in the entity with a item, and do not register it using the globalID.

 

This should show what i mean by vanishing..

im not using globalID,

 

Yes you are, its in your post:

int i =EntityRegistry.instance().findGlobalUniqueEntityId(); //GlobalID
EntityRegistry.registerGlobalEntityID(RobotHelper.class,"robotHelper",i); //GlobalID

 

egg dont work without it, but i spawn in the entity with a item, and do not register it using the globalID.

 

Yes they do, use the registerModEntity overloaded function that takes two color parameters.

I posted the old way and the new way, new way will only spawn pig, dont matter if you use the function that create the egg as well as register it, or register the egg manually.

 

I was just listing both as i believe i was doing it wrong since the new way was not working correctly, I now know that is caused by a current bug in forge that is being corrected, https://github.com/MinecraftForge/MinecraftForge/pull/2587

 

Main problem now seems to be any entity or modded entity at least will vanish when a map is reloaded, the entity is still alive, can take damage, and will collide with the player, but is not visible until some update is triggered, like in the video i posted i use ender pearls to teleport threw the entity making me coolide with it causing some damage and the entity is then visible.
