Another question

[DarthRaff]

Hello,

 

I have that code that works perfect:

require("scripts/class")
require("Scripts/constants/engine_const")
local class=CreateClass(...)
function class:InitDialog(grid)
self.super:InitDialog(grid)
group=grid:AddGroup("Rotation")
    group:AddProperty("rotationspeed",PROPERTY_VEC3)
--group:AddProperty("rotationspeed",PROPERTY_FLOAT)
end
function class:CreateObject(model)
    local object = self.super:CreateObject(model)
    object.model:SetKey("rotationspeed","0.0,1.0,0.0")
--object.model:SetKey("rotationspeed","1.0")
function object:SetKey(key,value)
 if key=="rotationspeed" then
  self.rotationspeed = StringToVec3(value)
  --self.rotationspeed=(value)
 else
  return self.super:SetKey(key,value)
 end
 return 1
end
function object:Update()
 if KeyHit(KEY_E) == 1 then
  self.rotationspeed.y=self.rotationspeed.y*-1
  --self.rotationspeed=self.rotationspeed*-1
 end
 model:Turn(self.rotationspeed,0)
    end
end

 

If i comment the rotationspeed Vec3 property and uncomment the rotationspeed float property, and the other changes, it doesn't work. I try to look in the scripts and models folders to do my self but can't find the solution.

 

I want to use just a float version of the rotationspeed property. can someone, please, help me ? thank you

i havent tried your code to see what else would be wrong, but the TurnEntity command is looking for a Vec3... so just change that line:

model:Turn(self.rotationspeed,0)

to:

model:Turn(Vec3(0,self.rotationspeed,0),0)

 

just playing around with the script, but this allows you to set the speed via the property dialog and pressing 'E' will rotate it opposite of current speed.

require("scripts/class")
require("Scripts/constants/engine_const")
local class=CreateClass(...)

function class:InitDialog(grid)
  self.super:InitDialog(grid)
  group=grid:AddGroup("Rotation")
  group:AddProperty("rotationspeed",PROPERTY_FLOAT,"2|-10,10,0")
  group:Expand()
end

function class:CreateObject(model)
  local object = self.super:CreateObject(model)
  object.model:SetKey("rotationspeed", 1.0)

  function object:UnlockKeys()
     self.rotationspeed = self.model:GetKey("rotationspeed")
  end

  function object:Update()
     if KeyHit(KEY_E)==1 then
        self.rotationspeed = self.rotationspeed*-1
        self.model:SetKey("rotationspeed", self.rotationspeed)
     end
     model:Turn(Vec3(0,self.rotationspeed,0),0)
  end
end

Thank you very much, that's what i looking for by now. I'm try to translate a door system in lua. I have it working on c++ but i want to see the behaviour of the system in the editor. Thank you again

[macklebee]

for a door i would probably use RotateEntity so you have control over the open/close angle easily... then have the controller send a message to the door if its picked to either open/close the door...

[Canardia]

I would use a physics door, because then you have automatically all the logic to block access to the room. Instead of TurnEntity, just use SetBodyOmega with CalcBodyOmega.

[DarthRaff]

Ok, thank you everybody, i will try

[Guest Red Ocktober]

i would use neither of the above (don't beat me up Mack, Mika ), and settle for a simple animated door, with a simple physics blocker, and a trigger region...

I tried using an animated door but ran into culling problems where the door would disappear whilst seemingly in view. It turned out to be a bounding box issue. If you use animated doors you'll need to take this into account. Here is the advice I was given by Josh:

 

The pivot itself doesn't matter, it's the bounding box. I recommend against making mechanical objects (like a door) a skinned mesh because it is more expensive to render, and there is no reason to use skinning. But in any case, if an animated mesh has animations that cause vertices to move far away, so that the object's bounding box is totally redefined, you should add a couple of vertices in the model to make sure the original bounding box encompasses the object's vertices when animated.

 

I settled for a simple rotation, as suggested by Mack above, in the end.

[DarthRaff]

Yes, i'm agree with Mack and Pixel, i tried it before, out of the editor, and works very well.
