Heroes and other plugins alike can modify the player health pool and after sometime sifting through their code, I couldn't figure out how they were doing it. Are they modifying the amount of damage done to the player? It would be wonderful if someone could inform me on how this is being done.
Indeed, you obviously can't add hearts to the player's life pool server side, but you can reduce its damage systematically. Check out the EntityDamageEvent : http://jd.bukkit.org/doxygen/d0/dfe/classorg_1_1bukkit_1_1event_1_1entity_1_1EntityDamageEvent.html
Yea, if you do something like event.setDamage(event.getDamage() / 2); in the event you would emulate a health bar 2x the size of a normal. A problem could be handling a damage of one, as the damage uses ints you can't set 0.5...
Yes, they're setting the damage value of the event. Now, since the health is stored as an integer, it's not possible to simply remove 0.5 health. But you can do one of two things: Use a HashMap to store the actual health of a player. This value would be under your control, so you could easily set the maximum to 100 instead of 20. Then, whenever the player receives damage you decrement your own health variable with that amount instead. Then you set the damage amount to: Code: int correspondingHealth = (int) (event.getPlayer().getMaxHealth() * (YOUR_MAXIMUM / (double)YOUR_VARIABLE)); event.setDamage(event.getPlayer.getHealth() - correspondingHealth); Handle fractional damage values by using Math.random() to either round up or round down. So, if you have a damage value of 0.4, you should give the chance of rounding down 60% and rounding up 40%. This is basically what I did in ExperienceMod, though for experience instead of damage. You can find my implementation here.
Oh, I didn't really. But armor damage mitigation is multiplicative, so it doesn't matter if you apply the damage reduction before or after. A * B = B * A, you know.
But event.getDamage() doesn't include damage reduction from armour. Health will decrease like there is no armour. Or am I missing something? You will be removing -5 damage from the custom variable whether the player has armour or not. Also you can write [A,B] = 0
Make a method to get the players armor strength: PHP: public double getDamagedReduced(Player p){ org.bukkit.inventory.PlayerInventory inv = p.getInventory(); ItemStack boots = inv.getBoots(); ItemStack helmet = inv.getHelmet(); ItemStack chest = inv.getChestplate(); ItemStack pants = inv.getLeggings(); double red = 0.0; if(helmet.getType() == Material.LEATHER_HELMET)red = red + 0.04; else if(helmet.getType() == Material.GOLD_HELMET)red = red + 0.08; else if(helmet.getType() == Material.CHAINMAIL_HELMET)red = red + 0.08; else if(helmet.getType() == Material.IRON_HELMET)red = red + 0.08; else if(helmet.getType() == Material.DIAMOND_HELMET)red = red + 0.12; // if(boots.getType() == Material.LEATHER_BOOTS)red = red + 0.04; else if(boots.getType() == Material.GOLD_BOOTS)red = red + 0.04; else if(boots.getType() == Material.CHAINMAIL_BOOTS)red = red + 0.04; else if(boots.getType() == Material.IRON_BOOTS)red = red + 0.08; else if(boots.getType() == Material.DIAMOND_BOOTS)red = red + 0.12; // if(pants.getType() == Material.LEATHER_LEGGINGS)red = red + 0.08; else if(pants.getType() == Material.GOLD_LEGGINGS)red = red + 0.12; else if(pants.getType() == Material.CHAINMAIL_LEGGINGS)red = red + 0.16; else if(pants.getType() == Material.IRON_LEGGINGS)red = red + 0.20; else if(pants.getType() == Material.DIAMOND_LEGGINGS)red = red + 0.24; // if(chest.getType() == Material.LEATHER_CHESTPLATE)red = red + 0.12; else if(chest.getType() == Material.GOLD_CHESTPLATE)red = red + 0.20; else if(chest.getType() == Material.CHAINMAIL_CHESTPLATE)red = red + 0.20; else if(chest.getType() == Material.IRON_CHESTPLATE)red = red + 0.24; else if(chest.getType() == Material.DIAMOND_CHESTPLATE)red = red + 0.32; return red; } Multiply the damage by 1-Armor Strength
Where did you get those values. Also, what about durability. I my plugin has been using the round up/down method, but I want to change it to hp method. I had real trouble implementing it.
I got this from a forum page a couple weeks ago, and durability doesn't affect armor strngth since like 1.8
Comphenix gamerzap Tried implementing this and failed miserably. The problem is that if you can't account for armour, because the amount absorbed is random. I did some tests and it seems that it rounds the actual damage up or down based on how close the damage is to those integers (4.4 gives 60% for 4.0 and 40% for 5.0). You can take control of the event, by setting the damage to 0 and damaging with entity.damage(...), but you will loose some sounds when doing that (bone cracking when falling).
It is actually possible to change the maxHealth field in CraftBukkit using nms. But, an additional health calculation is the needed when sending messages to the client, and I have no idea how you can prevent that. Maybe overriding the 'player stats packet' with your own that has this health factor in mind.
