Storing data to entities and other scripting tricks

[JKos]

We cannot define new real components(Classes) and userdata is actually ScriptComponent so if you want to do that dynamically you have to do something like this.

Code: Select all

entity:createComponent('Script','data')
entity.data:setSource([[
data = {}
function get(self,name)
   return self.data[name]
end
function set(self,name,value)
   self.data[name] = value
end
]])

NOT tested so please tell if this works.

Thanks a lot JKos, I will pretty soon.

Sorry, but with theses info, I can't even add userData as a component on pre created object (not at runtime, I still have to check)

At runTime, here is how I use your script:
I have a function that create item, and give it/changes various components.

then at some point I have this:

Code: Select all

spawnthing:createComponent('Script','data')
spawnthing.data:setSource([[
data = {}
function get(self,name)
   return self.data[name]
end
function set(self,name,value)
   self.data[name] = value
end
]])

local deteriorationValue = 10+(math.random(1,15))
spawnthing.data:set("maxDeterioration", deteriorationValue)
spawnthing.data:set("Deterioration", deteriorationValue)

Error code is "attempt to call method set (a nil value)"

I tested it too and it really doesn't seem to work, which is a bit strange because with script_entity setSource and loadFile works. But anyway, if you are using cloneObject you can easily add those data-components to desired objects in init.lua.

cloneObject:
viewtopic.php?f=22&t=8450

then in init.lua

Code: Select all

local addUserDataToThese = {'dagger','herder','ratling1','etc...'}
for _,entname in ipairs(addUserDataToThese) do
  cloneObject{
      name=entname,
      components = {
           userData
      }
   }
end

thanks JKos. I think I will humbly use tables for some times

Ok, would it be nice if you could store entity specific data directly to the entity? Like:
crab_1.data:set('is_boiled',true)
and access that data like this:
crab_1.data:get('is_boiled')

How would I call these functions using delayedCall?

spawnthing.data:set("maxDeterioration", deteriorationValue)
spawnthing.data:set("Deterioration", deteriorationValue)

When you call setSource or loadFile, the passed string doesn't get executed immediately. So the component doesn't have the "get" and "set" fields yet in your example, because the script entity source hasn't been run yet. In this example it might never run at all, I haven't actually been able to figure out when it does, but I'm pretty sure the setSource or loadFile call has to be before the ScriptComponent actually initializes.

(I got this idea from Xanathar's GrimQ library for LoG1, sorry for copying your ideas if you happen to read this . I loved those autoexec-scripts)

My progress reading this thread:

• Wow that's a smart way to embed scripts in other entities
• Auto objects!! That's what I need in my Orrr3 room !
• Wooooh thanks mate! You're welcome!

OMG This Post is so far the best AUTO everything This is saving a lot of extra objects on the field eg: floor_trigger connected to script entity.... Now I just use the script entity no more floor_triggers yeeeeeeeeeeeeeeeeeeeee THXS SO MUCH JKOS Love you bro

EDIT: How do I add this to Lever, wall button and torch I tried and I cannot get it to work lol

EDIT2: Ok I think I got it. I hope this is right:

Code: Select all

defineObject{
   name = 'script_autotrigger_button',
   baseObject = 'script_entity',
    components = {
	{
	class = 'Button',
	sound = 'button',
	},
	{
	class = "Model",
	model = "assets/models/env/wall_button.fbx",
	},

	{
	class = "Animation",
	animations = {
	press = "assets/animations/env/wall_button_press.fbx",
	}
	},
	{
	class = "Clickable",
	offset = vec(0,1.375,0),
	size = vec(0.25, 0.25, 0.25),
	--debugDraw = true,
	},
	{
	class = "Script",
	source = [[
function execute(trigger)
   -- your code here
end
self.go.button:addConnector('onActivate',self.go.id,'execute')
         ]]
      }
    }
}
