Copy Mob Effects to MC1.18 archive
A <code>MobEffect</code> is what handles the specific logic on the entity it is on. For example, <code>MobEffects#MOVEMENT_SPEED</code> adds an attribute modifier that affects the movement speed while <code>MobEffects#WITHER</code> attacks the entity from a <code>DamageSource</code> whenever the mob effect is ready to be applied.
== Creating a <code>MobEffect</code> ==
You can create a <code>MobEffect</code> using two methods. The first creates a regular <code>MobEffect</code> and applies the logic in some event method. The other method involves extending the <code>MobEffect</code> class and overriding specific methods when needed. This documentation will focus on the second method.
There are four methods that are important depending on the type of mob effect you are creating. In each scenario, you should take into account whether you should extend <code>MobEffect</code> or <code>InstantenousMobEffect</code>.
Here are the classes and methods to review:
{| class="wikitable sortable" border=1
!Class !!Usage
|-
| <code>MobEffect</code> || The basic mob effect class. Should be used if the mob effect happens over time.
|-
| <code>InstantenousMobEffect</code> || An extended version of the mob effect class. Should be used if the mob effect happens only once and instantly.
|-
|}
{| class="wikitable sortable" border=1
!Method !!Description
|-
| <code>isDurationEffectTick</code> || Determines how fast a mob effect should call <code>applyEffectTick</code> while applied. This is overridden by <code>InstantenousMobEffect</code> to occur after one tick. If too fast, the server will not have enough time to execute the damage on the entity.
|-
| <code>applyEffectTick</code> || Executes the logic on the entity when called.
|-
| <code>isInstantenous</code> || Determines if the mob effect is instant. Returns true in <code>InstantenousMobEffect</code>.
|-
| <code>applyInstantenousEffect</code> || Executes the logic on the entity when called. <code>isInstantenous</code> must return true for this to be called.
|-
|}
If you are only modifying an entity <code>Attribute</code>, then there is no need to extend the class. When constructing the mob effect instance, chain <code>addAttributeModifier</code> and select the specific attribute, it's unique id, the amount to affect by, and the operation to apply the amount with.
Mob Effects need to be [[Registration/1.18|registered]].
== <code>MobEffectInstance</code> ==
To allow greater customization, each mob effect is passed in as a <code>MobEffectInstance</code> which allows the user to specify additional information for what the mob effect should do.
