Delay Time of Death

[TheSAguy]

Hi,

In my Natural Evolution Enemies mod, I have worms shoot units to the player.
The way it works is that I create a trigger entity that I kill and then spawn the units.

Currently it's instantaneously and I'd like to only like to spawn the newly created units like 5 seconds later. or in other words, kill the trigger entity in 5 seconds after it's created.

Here is the current code:

Code: Select all

script.on_event(defines.events.on_trigger_created_entity, function(event)
	
	local entity = event.entity	

	--- Unit Cluster created by Worm Launcher Projectile 
    if entity.valid and global.launch_units[entity.name] then
		writeDebug("Cluster Unit Created")
		entity.die()
    end
	
end)

Thanks.

Well, the initial event, I'd look at how capsules work, since using a capsule fires a projectile, the same methods can be used to create entities when the projectile explodes.

a 5 second delay... hmmm...
Keep in mind I haven't done this, but...could you create an animation (it can even be invisible, the point is the entity exists) that lasts for 5 seconds, and then creates the new entity when it ends?

Yeah, I like to keep scripts out of it whenever possible.

So they way it currently work is the projectile fires and then I create a little unit at the end and kill it.
When it dies, I spawn the other units.

So how would I direct if an animation is done to then do something?

I tried giving the created unit 5 life and give it a negative health gain of -1, so it die after 5 ticks, but that approach does not seem to work.

Thanks.

Maybe creating a 'SmokeWithTrigger' will solve your problem?

It can have a cooldown of 5 seconds, with the action of createEntity

This is what I was trying to describe.

The best part is that if you do it correctly, you don't have to use scripts at all!

fire weapon
projectile hits target, creates a SmokeWithTrigger entity
SmokeWithTrigger entity expires in 5 seconds, and spawns an enemy unit.

Thanks guys, I'll give this a shot.

Okay, so I'm still not exactly sure how to implement the smoke-with-trigger. since my trigger, is still triggered when the smoke is created and not when the duration ends.

I have my Projectile as: (I removed the sound and animation in below code)

Code: Select all

--- Unit Projectile
  {
    type = "projectile",
    name = "Unit-Projectile",
    flags = {"not-on-map"},
    acceleration = 0.005,
	force = "enemy",
    action =
    {
      type = "direct",
	  force = "enemy",
      action_delivery =
      {
        type = "instant",
		force = "enemy",
        target_effects =
        {
	  
          {
            type = "create-entity",
			force = "enemy",
			entity_name = "ne_unit_launcher_trigger",
			
          },
        }
      }
    },

  },

Then I have my trigger entity as:

Code: Select all

	--- Unit Launcher Smoke that will cause the Trigger
	Unit_Launcher_Trigger = table.deepcopy(data.raw["smoke-with-trigger"]["poison-cloud"])
    Unit_Launcher_Trigger.name = "ne_unit_launcher_trigger"
	Unit_Launcher_Trigger.duration = 60 * 20
	Unit_Launcher_Trigger.fade_away_duration = 0
	Unit_Launcher_Trigger.spread_duration = 0
	Unit_Launcher_Trigger.force = "enemy"
	Unit_Launcher_Trigger.action = {
      type = "direct",
	  force = "enemy",
      action_delivery =
      {
        type = "instant",
		force = "enemy",
        target_effects =
        {
            type = "create-entity",
			force = "enemy",
			entity_name = "blood-explosion-big",
			trigger_created_entity = true,
        },

      }
    }

	data:extend{Unit_Launcher_Trigger}

In control I have:

Code: Select all

script.on_event(defines.events.on_trigger_created_entity, function(event)
	
	local entity = event.entity	


	--- Event triggers on the creation and not completion of the smoke.
	if entity.valid and entity.name == "blood-explosion-big" then 
		writeDebug("Unit Triggered")
    end
	
end)

Thanks.
