Script for Animating a Part of an Object **HELP**

[02arnoldj]

Hi im using the Leadwerks Engine 2.5 Evaluation ver. I could do with the Script to animate a part of an object, I.E The Windmill's Blades. Also How to animate a character in the engine ? I have a character and the animations work in the Model Viewer but not in the engine?

 

Thanks guys

TY -We making Progress now,

 

We got the gun to animate in lua so we done a reload sequence that loads 3 sound files Clip being pulled the clip back in and the ****: Then we play them at key frames.

 

Now the thing we need to do is we need to make a script that we can use for any object that has animation files.

That script will play the ide frames of the object/Character.

 

I have look about all day I tried to make it up but get errors.

I saw you explained to some1 a way that referenced actor:Play actor:Draw

 

I tried the examples and I got errors again.

 

When a entity is placed into Editor Im guessing it builds up a table with location/Size ect does it contain frames I am using the crawler So We know it has them but do you need to tell it they are there.?

 

Is it possible to create scripts for characters in Lua that control AI of that character.

then in c load the scene and control cam using keys but the characters use there scripts so move around?

 

That way the AI will be Per Object and the game code becomes simple.

 

2 days to play gun animations! we could do with the help!

Here is a character animation template i wrote for the leadwerks community project in lua

We got the gun to animate in lua so we done a reload sequence that loads 3 sound files Clip being pulled the clip back in and the ****: Then we play them at key frames.

 

Now the thing we need to do is we need to make a script that we can use for any object that has animation files.

That script will play the ide frames of the object/Character.

well if the animations are all in one file then you have to tell LE what frames are doing what animation... if the animations are separate files with similar names and loaded using LoadAnimation then you can probably make a generic animation script to work for any object. But just starting out with LE, you should probably focus on just understanding how LE works instead of trying to optimize a script to be used in any situation... Go through the link Josh provided and read it. Then read it again until you understand how animation works in LE. and then compare it to what Chris just provided.

 

I have look about all day I tried to make it up but get errors.

I saw you explained to some1 a way that referenced actor:Play actor:Draw

 

I tried the examples and I got errors again.

You need to realize there are two engines at the moment. LE2.5 is the evaluation version that you can currently download. LE3 is the rewritten engine that has not been released yet. 'actor:Play' & 'actor:Draw' are from LE3.

 

When a entity is placed into Editor Im guessing it builds up a table with location/Size ect does it contain frames I am using the crawler So We know it has them but do you need to tell it they are there.?

yes

 

Is it possible to create scripts for characters in Lua that control AI of that character.

then in c load the scene and control cam using keys but the characters use there scripts so move around?

yes

 

You and I assume your partner Mince have posted questions about the windmill model. That is not using animation sequences to rotate. The script is simply rotating a child mesh - blades- of the model. But I am curious on where you got that model from?

[Guest Red Ocktober]

if you're referring to the windmill in the old Leadwerks ( version 2.26 ? )... here's a lil bit of old code that i found when i did the same thing you're trying to do... the code is from an old experiment in object oriented programming in BlitzMax, so it's probably not relevant to the current version of Leadwerks... and then again, maybe it's still good...

 

anyways... there should be enough there and it should be obvious enough answer your question about getting that windmill to spin...

 

in short, i found the windmill object in the scene, then found the windmill blades (child object)... then spun it during the update...

 

 

Type TWindmill Extends TGameObject
Field picked :TPick
Field myLoc :TVec3
Field myRot :TVec3
Field listLink :TLink
Field wasPicked :TGameObject
Field lastSqueak :Int
Field squeak :TSound[]=[LoadSound("abstract::squeak_1.ogg"),LoadSound("abstract::squeak_2.ogg")]
Field foundChild :Int=0

Method Update(context:Object)

If GAME.GameObjectsList<>Null
' find the view cam location... were gonna need it in a sec
Local viewLoc:TVec3=EntityPosition(GAME.fw.Main.camera)
' find the windmill blades... they're gonna have to spin, not the whole windmill
Local theBlades:TEntity=FindChild(Self.mesh,"windmill_blades")

' get a link to the windmill in the gameobjects list
' so we can retrieve the value contained in the link
listLink=GAME.GameObjectsList.FindLink(Self)

' get the type of the object in the link in prep for pick test
 wasPicked= TGameObject(listLink.value())

' get the location of this object in case it is picked
 myLoc=EntityPosition (wasPicked.mesh)
 myLoc.y=myLoc.y+2

' only do the following block for this instance if in the list
' this is what makes each gameobject instance an individual
If Self
 If(TWindmill(context).mesh<>Null) Then TurnEntity theBlades,Vec3(0,GAME.windSpeed/5,0)

    ' Make the base squeak
    Local lasttime:Int=lastSqueak
    If (AppTime()-lasttime>3000)
    lastSqueak=AppTime()+ Rand(0,2000)
    EmitSound(theBlades,squeak[Rand(0,1)],80,1)
  EndIf
 EndIf
EndIf

EndMethod

 

sorry i can't be of more help... i just remember this vaguely from way back...

the cut and paste has the formatting all screwed up...

even though it's BlitzMax code it should be easy enough to see what's going on

and translate the relevant parts... the rest is just my OOP stuff and can be disregarded

[Guest Red Ocktober]

hey... me again... THANKS for posting your question... got me interested in moving the Windmill over to 2.5 and getting stuff working in lua only...

 

does your lua code look anything like this...

 

--Include the base script for all classes
require("scripts/class")
require("scripts/linkedlist")
require("scripts/table")
local class=CreateClass(...)
--Some global sounds we will use for all instances
squeak={}
squeak[0]=LoadSound("abstract::squeak_1.ogg")
squeak[1]=LoadSound("abstract::squeak_2.ogg")

--This function builds the interface for the properties editor
function class:InitDialog(grid)
--Add the base interface for all classes
self.super:InitDialog(grid)

  --Now we can add our own custom properties
  group=grid:AddGroup( "Windmill" )
  group:AddProperty( "spinspeed","|0,4",PROPERTY_FLOAT,"Spin Speed")
group:Expand(1)

end
function class:CreateObject(model)	  
 local object=self.super:CreateObject(model)	   
 function object:Render()					   
 --  frame = (AppTime()/35.0) % (300-0) + 1					   
 --  model:Animate( frame, 1,0, 1 )				
 end
end

--Spawn function for creating new instances
function class:CreateObject(model)
local entity=self.super:CreateObject(model)

--Retrieve a few limbs we will use later
entity.blades=model:FindChild("windmill_blades")
entity.base=model:FindChild("windmill_housing")
entity.model:SetKey("spinspeed","1")
--An update function for one instance.  Declaring the function as part of the entity table allows us to use "self" for the table
function entity:Update()

 --Although these limbs should always be present, it"s a good idea to add a check to make sure they exist before using them
 if self.blades~=nil then
  self.blades:Turnf(0,tonumber(self.model:GetKey("spinspeed"))*AppSpeed(),0,0)
 end

 if self.base~=nil then

  --Make the base sway slightly
  angle=math.sin(AppTime()/2000.0)*5-15
  angle=angle+math.cos(AppTime()/500.0)*2
  self.base:SetRotationf(0,0,angle,0)

  --Make the base squeak
  lasttime=tonumber(self.model:GetKey("lastsqueaktime","0"))
  if (AppTime()-lasttime>8000) then
   self.model:SetKey("lastsqueaktime",AppTime()+math.random(0,5000))
   self.base:EmitSound(squeak[math.random(0,1)],50,1,0)
  end
  lasttime=tonumber(self.model:GetKey("lastsheeptime","0"))
 end

end
end

--Update function, called during every UpdateWorld()
function Update(world)
if world==world_main then
 local model,entity
 for model,entity in pairs(entitytable) do
  if model.world==world then
   entity:Update()
  end
 end
 end
end

[macklebee]

why do you have two functions for CreateObject? and why are you not using the standard object functions?

[Guest Red Ocktober]

while getting it to work i was doin' some copying and pasting... that extra function snip should've been deleted...

 

hhhmmmm wonder why no error... looking now...

 

--Mike

[macklebee]

well here is just a simple version that uses the current standard object functions to show how to turn the windmill blades:

require("scripts/class")
local class=CreateClass(...)

function class:InitDialog(grid)
  self.super:InitDialog(grid)
  group=grid:AddGroup( "Windmill" )
  group:AddProperty( "spinspeed","|0,4",PROPERTY_FLOAT,"Spin Speed")
  group:Expand(1)
end

function class:CreateObject(model)
  local object = self.super:CreateObject(model)
  object.blades = model:FindChild("windmill_blades")
  object.model:SetKey("spinspeed","1")

  function object:Update()
     if self.blades~=nil then
        self.blades:Turn(Vec3(0,tonumber(self.model:GetKey("spinspeed"))*AppSpeed(),0))
     end
  end
end

 

granted due to the mesh heirarchy, about the only way this is useable is to have it converted directly from fbx... majority of the people here that use uu3d for conversion lose out on this nice little feature...

[Guest Red Ocktober]

cool... and a lot cleaner...

 

*** edited ***

(i just found a version with 2 functions, similar to the one you just posted... it's been so long since i played with this, it's gonna take me a while to get back on track with this stuff)

 

 

hey... why can i not get the blades to spin if i load the scene from a lua script...

it works fine in the editor, bmax, c++ ??

 

 

--Mike

[macklebee]

works for me... maybe check out the engine.log file and see if its loading correctly?

[Guest Red Ocktober]

roger... copy...

 

thx

 

** edited ***

(yup... the abstract path was set to ""... setting it properly did the trick...

what a dope i am early in the morning)

[02arnoldj]

Thanks Red & Macklebee. Got that done.

The aim was that if we can get a limb to rotate,

we could have a gun like a minigun with the barrels spinning but when we try this it come up with attempt to index a global =nil.

 

In the windmills case it uses class, and is a script of a object that has been dropped in the editor.

 

In this case We have a script that loads a gun and some sounds, and it all worked great.

We then made a minigun in 3dsmax and tried to adapt the windmill code to rotate the barrels. this is when we get the error

[macklebee]

Without seeing the actual model and script in question, all anyone can do is guess at what you are doing wrong. The windmill model this works correctly for... maybe there is a problem with your model. If you really want someone to help you, then zip up the model/script and post here.

[02arnoldj]

So the Lua Script following Will show the reload animation frames of smg.

then we added the minigun bits

[02arnoldj]

--added to top

local minigun = LoadMesh("abstract::minigun.gmf")

 

 

--tried it with requires script& class = create script

--that didnt work either.

 

 

-added at top

object.barrels = model:FindChild("barrels")

 

minigun:SetParent(fw.main.camera,0)

minigun:SetPosition(Vec3(-0.15*gunscale,-0.04*gunscale,0.25*gunscale),0)

minigun:SetScale(Vec3(0.03*gunscale,0.03*gunscale,0.03*gunscale))

local gundisplayposition = minigun:GetPosition()

 

 

 

--Added to main loop

if MouseDown(1)==1 then

if gun==2 then

if self.barrels~=nil then

self.barrels:Turn(Vec3(0,1*AppSpeed(),0))

end

end

end

local minigun = LoadMesh("abstract::minigun.gmf")
object.barrels = model:FindChild("barrels")

 

Since you are loading the mesh just be aware that this does not load the minigun's object script. The next line does not work because this is a game script and not an object script. So 'object.barrels' means nothing and model is not referencing the minigun.

 

If you are trying to find the child mesh in the minigun GMF then you have to reference the minigun

local minigun = LoadMesh("abstract::minigun.gmf")
local barrels = minigun:FindChild("barrels")

You should still post the model to confirm that you have mesh hierarchy in the GMF. Also this can be verified in the modelviewer and you can do a logic check to make sure its found by checking to make sure barrels is not equal to nil.

would instead;

we have a lua for mini gun that receives messages, and the fps lua would send message to that mini gun?

[02arnoldj]

TY I think I did try that, We really appreciate the help.

I have not any space left to host minigun.zip for you to see. can we upload here?

using minigun instead of object gave me a error attempting to index a global object with nil value,

Does that mean It cant find the actual files?

[macklebee]

are you still using 'object.barrels' in the game script? if so, stop it and do what i showed you to do.

 

if you are getting the error because 'barrels' is actually nil then you need to perform a logic check to see if it actually found the child mesh called 'barrels'. If this is happening then I can assume your model doesnt actually have mesh hierarchy.

 

and you should try to make a simpler standalone version that just focuses on loading the minigun and finding the child mesh if it exists.
