最近突发奇想的一个问题，我指的这个计算公式是对任何实体（能移动且不免疫摔落伤害的）的，在别的地方找了一下，好像也只有玩家的摔落伤害的计算公式...
貌似玩家和其他实体的计算方式都是通用的
掉落伤害代码于net.minecraft.entity.EntityLivingBase中 (从代码位置也能看出来是生物通用的)
- super.fall(distance, damageMultiplier);
- PotionEffect potioneffect = this.getActivePotionEffect(MobEffects.JUMP_BOOST);
- float f = potioneffect == null ? 0.0F : (float)(potioneffect.getAmplifier() + 1);
- int i = MathHelper.ceil((distance - 3.0F - f) * damageMultiplier);
- if (i > 0)
- {
- this.playSound(this.getFallSound(i), 1.0F, 1.0F);
- this.attackEntityFrom(DamageSource.fall, (float)i);
- int j = MathHelper.floor(this.posX);
- int k = MathHelper.floor(this.posY - 0.20000000298023224D);
- int l = MathHelper.floor(this.posZ);
- IBlockState iblockstate = this.world.getBlockState(new BlockPos(j, k, l));
- if (iblockstate.getMaterial() != Material.AIR)
- {
- SoundType soundtype = iblockstate.getBlock().getSoundType();
- this.playSound(soundtype.getFallSound(), soundtype.getVolume() * 0.5F, soundtype.getPitch() * 0.75F);
- }
- }

掉落伤害公式
- 伤害=向上取整((距离-3-跳跃提升buff强度)*方块伤害倍率)
如果生物在飞行状态下下降速度不大于10格每秒或者不处于下降状态时认为距离为1
net.minecraft.entity.EntityLivingBase中
- if (this.isElytraFlying())
- {
- if (this.motionY > -0.5D)
- {
- this.fallDistance = 1.0F;
- }

生物在爬梯子状态下掉落距离归零
net.minecraft.entity.EntityLivingBase中- if (this.isOnLadder())
- {
- float f9 = 0.15F;
- this.motionX = MathHelper.clamp(this.motionX, -0.15000000596046448D, 0.15000000596046448D);
- this.motionZ = MathHelper.clamp(this.motionZ, -0.15000000596046448D, 0.15000000596046448D);
- this.fallDistance = 0.0F;
- if (this.motionY < -0.15D)
- {

生物当被骑上的一瞬间掉落距离归零
net.minecraft.entity.EntityLivingBase中- public void updateRidden()
- {
- super.updateRidden();
- this.prevOnGroundSpeedFactor = this.onGroundSpeedFactor;
- this.onGroundSpeedFactor = 0.0F;
- this.fallDistance = 0.0F;
- }

任意实体在水里掉落距离归零
net.minecraft.entity.Entity中- public boolean handleWaterMovement()
- {
- if (this.getRidingEntity() instanceof EntityBoat)
- {
- this.inWater = false;
- }
- else if (this.world.handleMaterialAcceleration(this.getEntityBoundingBox().expand(0.0D, -0.4000000059604645D, 0.0D).contract(0.001D), Material.WATER, this))
- {
- if (!this.inWater && !this.firstUpdate)
- {
- this.resetHeight();
- }
- this.fallDistance = 0.0F;
- this.inWater = true;
- this.extinguish();

任意实体在蜘蛛网里掉落距离归零
net.minecraft.entity.Entity中- public void setInWeb()
- {
- this.isInWeb = true;
- this.fallDistance = 0.0F;
- }
|
等等...
我感觉我甚至在抄维基百科
顺便一提, 比较冷门的知识点
如果一个生物掉出世界的话, 她的掉落距离将加上y轴坐标的绝对值(在1.12中)
比如说一只苦力怕在虚空y=-10中呆着, 她的掉落距离将会被加上10
- else if (y < 0.0D)
- {
- this.fallDistance = (float)((double)this.fallDistance - y);
- }
|
然后如果一个生物被骑着的话, 掉落伤害也会传递到骑着她的生物上
- public void fall(float distance, float damageMultiplier)
- {
- if (this.isBeingRidden())
- {
- for (Entity entity : this.getPassengers())
- {
- entity.fall(distance, damageMultiplier);
- }
- }
- }
