SackCastellon Posted March 19, 2014 Posted March 19, 2014 How can i make a player invisible to mobs on wearing an specific armor set, by the way the player is not been attacked by them. I've tried this, but the mobs still attack the player: player.addPotionEffect((new PotionEffect(Potion.invisibility.id, 2, 0))); Thanks for helping. Quote
TLHPoE Posted March 19, 2014 Posted March 19, 2014 I'm not sure if this would be the most efficient way, but: 1. Setup an entity tick event 2. Check if entity is a mob 3. Check if mob has a target (the player) 4. Remove if it does Quote Kain

TheGreyGhost Posted March 21, 2014 Posted March 21, 2014 Hi This has some useful code http://www.minecraftforum.net/topic/1419836-131-forge-4x-events-howto/ Not sure how you would cancel the event, it doesn't seem to be cancelable like normal events, unless I'm missing something. You could perhaps use @ForgeSubscribe public void entityTarget(LivingSetAttackTargetEvent event) { if (event.target != null && event.target instanceof EntityPlayer) { event.entityLiving.setAttackTarget(null); } } Not sure if that will work since the call to setAttackTarget is reentrant, i.e. will trigger another LivingSetAttackTargetEvent. Also, setting target to null like this might perhaps cause a crash. And, probably, the mobs will just stand around doing nothing instead of ignoring the player. But it's worth a try :-) -TGG Quote
coolAlias Posted March 21, 2014 Posted March 21, 2014 What TGG said, though if you check properly the second post to the set living attack target event should process just fine. Btw, checking instanceof automatically null checks for you: if (event.target instanceof EntityPlayer) { ((EntityLiving) event.entity).setAttackTarget(null); } That will make the mobs mostly just stand around doing nothing, even if you attack them. If you want them to fight back, you should add the following check to the check for instanceof EntityPlayer: && event.entityLiving.func_94060_bK() != event.target) Note also that this only works on mobs that are using the AI system - spiders, for example, will still attack you.

Ok, thanks, it works. Now i have another problem: If the player is firstly invisible, then the mobs don't attack him, but if the mobs are attacking him and the player becomes invisible, the mobs still attack him. This is my code: /** * Only works with AI mobs: Zombies, Skeletons and Creepers. * @param event */ @SubscribeEvent public void onEntitySetTarget(LivingSetAttackTargetEvent event) { if (Loader.isModLoaded("SKC-Camouflage")) { if (event.target != null && event.target instanceof EntityPlayer && event.entityLiving.func_94060_bK() != event.target) { if (event.target.isInvisible()) { ((EntityLiving) event.entity).setAttackTarget(null); } } } } Quote

coolAlias Posted March 22, 2014 Posted March 22, 2014 You could subscribe to LivingAttackEvent as well, checking if the player is invisible and getting the source of the source of damage (yes, you read that right), checking if that is an EntityLiving and then setting their current target to null. Obviously that won't work for everything - creepers, for instance - but it should cover most. Otherwise, you could get all of the living entities nearby the player when they turn invisible and set their targets to null at that time, if their current target is the player turning invisible. Probably simpler to just deal with some mobs still attacking. Quote http://i.imgur.com/NdrFdld.png[/img]

coolAlias Posted March 24, 2014 Posted March 24, 2014 You don't know how to prevent class cast exceptions?

Solution: instanceof EntityLiving and EntityPlayer are both subclasses of EntityLivingBase, but you cannot cast one to the other unless it is an X instanceof Y (you can cast both to EntityLivingBase, if that's what you need, though.) SO, put an 'if' in there to catch that and use logic.

Stop confusing people with random comments. I don't find your attitude helpful. Perhaps you could keep your snide comments out of the fora. How is clarifying a statement that confuses the issue at hand being snide or unhelpful? I've seen you give people some excellent advice on challenging questions in other threads, but there have been several cases where you've been either plain wrong or providing extraneous information that diverts from the main point; in the latter cases, I feel it is indeed helpful to point it out and provide either clarification or correction as needed. When I say "stop confusing people with random statements", I'm referring to the latter; for the former, it is helpful to fact-check before posting replies to make sure the information you provide is accurate. If you consider that snide, well, that's your call. Quote http://i.imgur.com/NdrFdld.png[/img]

If you consider that snide, well, that's your call. Your remarks were and continue to be out of band for these fora. Your tutorials are nice, but all you do is self-advertise your ability to learn from tutorials. So, when all you have to add is "hey, look at my totorial," you really don't have any place suggesting I change my posting habits to suit you. Now, please grow the hell up and stop this quibbling. It gains nothing and bores me.
