WorldsEnder Posted January 31, 2015 Share Posted January 31, 2015 Hi guys, I stumbled over something really, really weird today and I can't wrap my head around it. Suppose I have an entity (`entity`) and I want to execute some AI task on the server only. A few things I have noticed so far: The entities AI is ONLY getting executed on the CLIENT because the AITaskManager has an if clause that is true when `entity.isClientWorld()`. Now, nothing special, but that IS a problem. Where do I execute my AI (reliantly) on the server only? Secondly, I thought `world.isRemote` is `true` for clients but it turns out that #isClientWorld() return `!worldObj.isRemote()`. Can somebody enlighten me where to place my AI logic? What use is it to execute AI on Client only? Is world.isRemote true or false on Clients? Quote Link to comment Share on other sites More sharing options...

WorldsEnder Posted January 31, 2015 Author Share Posted January 31, 2015 The main part of the question is about the AI... why should the AI be executed ONLY on the Client and not on the Server, is there some secret I haven't found yet? How does target selection work if the AI is not present on the server at all? Also (real source from EntityLivingBase): public boolean isClientWorld() { return !this.worldObj.isRemote; } WHAT? WHAT???!?!?!?!? I can confirm that this returns true for the <s>CLIENT</s>SERVER?!?!! Edit: Eclipse tells me that world.isRemote is set to true wherever it is accessed.. unless the write-access find has bugs I can't understand why it should EVER be set to false Quote Link to comment Share on other sites More sharing options...
Mitchellbrine Posted January 31, 2015 Share Posted January 31, 2015 Ummm, shouldn't it be on both sides? Or am I wrong?

WorldsEnder Posted January 31, 2015 Author Share Posted January 31, 2015 Try it yourself or look at "EntityLivingBase#onLivingUpdate(), line 50", it says else if (this.isClientWorld()) { if (this.isAIEnabled()) { this.worldObj.theProfiler.startSection("newAi"); this.updateAITasks(); this.worldObj.theProfiler.endSection(); } //.... EDIT: I want the mod to run on an integrated server aswell, just so you know. Quote Link to comment Share on other sites More sharing options...
Mitchellbrine Posted January 31, 2015 Share Posted January 31, 2015 Apparently, isClientWorld() returns the opposite of world.isRemote, so that means it's on the server. So maybe, it isn't both sides, but it isn't the client if isClientWorld returns the opposite of world.isRemote.

WorldsEnder Posted January 31, 2015 Author Share Posted January 31, 2015 So basically isClientWorld() is just the most misleading name to give to a method that is supposed to return true for the server? kek Quote Link to comment Share on other sites More sharing options...
Mitchellbrine Posted January 31, 2015 Share Posted January 31, 2015 So basically isClientWorld() is just the most misleading name to give to a method that is supposed to return true for the server? Yep, the most deceiving name for a method. It would be better to name isRemote that, but tradition has kept isRemote the same.
