Animation with LODs

[Matthew Nicholls]

Can anyone please help with getting all the levels of detail to animate at the right time. I have 4 LOD models and an animation in an other gmf file. If I only have the one model in the folder and load the animation in to it, it animates fine. But when I have the 4 LOD models in the folder only the LOD4 animates. The main model and the LODs 1-3 all show at the right distance but they do not animate.

 

require("scripts/class")

local class=CreateClass(...)

function class:InitDialog(grid)
self.super:InitDialog(grid)
end

function class:CreateObject(model)
local object=self.super:CreateObject(model)

       object.model:SetLODDistance(5,0)
object.model:SetLODDistance(10,1)
object.model:SetLODDistance(20,2)
object.model:SetLODDistance(30,3)
object.model:SetLODDistance(40,4)

--Walk
object.frame_Walk = 1
object.sequence_Walk = LoadAnimation(object.model,"abstract::Animation_Walk_Normal.gmf")
object.framebegin_Walk = 1
object.frameend_Walk =31
object.blend_Walk = 1.0
object.animspeed_Walk = 50.0
object.recursive_Walk = 1


    function object:Update()
--Walk
self.frame_Walk  = AppTime()/self.animspeed_Walk
self.frame_Walk  = mod(self.frame_Walk , (self.frameend_Walk - self.framebegin_Walk)) + self.framebegin_Walk
self.model:Animate(self.frame_Walk,self.blend_Walk,self.sequence_Walk,self.recursive_Walk)

    end


function object:Free(model)	

	self.super:Free()
end

function mod(a,
	return a % b
       end
end

You actually want to load the animation onto each of the LOD meshes of the model. You can get them with the model:CountLodEntities() and model:GetLodEntity(i) commands. LOD meshes get removed from the model's children dynamically, so going through the children won't do it.

Thanks for the reply Josh. Would it look something like this?

 

for lod = 0 ,object.model:CountLodEntities() do 
	object.sequence_Walk = LoadAnimation(object.model:GetLodEntity(lod), object.animFilename)
end

 

Whatever I do with those two methods I get 'Index for object is not a valid field or method.' when I try to save the file

solved with macklebee's help

 

for lod = 0 , CountModelLODEntities(object.model) - 1 do 
	object.sequence_Walk = LoadAnimation(GetModelLODEntity(object.model,lod), object.animFilename)
end

Also, for those who want to see the new commands in action - I have updated Masterxilo's soldier script to include the change from 'object:Render()' to 'object:Draw()' and the new LE2.5 LOD commands shown above. The soldier.lua script is the only thing changed. The soldierGame.lua gamescript still is the same.
