Setting the Prop Collision for Models in Code

[dhutchison]

For each of the models I am using in LeadWerks (e.g., object.gmf), I have created an accompanying .lua file (e.g., object.lua) with the following code:

 

require("scripts/class")

local class=CreateClass(...)

 

When I open the Properties Inspector for a model in the editor, I need to manually set the Collision to "Prop".

 

What line(s) I should add to the code above, so I don't have to set this up manually each time? Thanks.

[macklebee]

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

function class:CreateObject(model)
local object=self.super:CreateObject(model)
object.model:SetKey("collisiontype","1")
end

[macklebee]

or just use those two lines like you have them and then make an INI text file for each of your models standard settings that would be found inside the class script/property dialog:

collisiontype = "1"
mass = "10.0"
etc... etc...

 

and then if you create a new instance of the object in a new scene it will automatically load these values.

Thanks. Works really well...

or...

 

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

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

So I can use a .ini file or set the parameters with

 

 object.model:SetKey("collisiontype","1")

 

for other property settings too?

[macklebee]

yes

When I add a copy of my stone model into my scene, the lua script (Josh posted) runs and I get the attached pic...

 

I originally used an INI file, and physics in the editor didn't work.

 

Any suggestions?

Hi,

Did you run that from script editor screen? (with F5 or Run)

[Rekindled Phoenix]

Yes, I ran that code using the editor.

 

The code also seems to be automatically run when I add the object into the world.

 

I still am a n00b at Lua, what do I do to solve this problem?

Do not run object scripts. Only save object scripts then add the object into the world.

 

You can run gamescripts like driver.lua or fpscontroller.lua in the editor. Or you can run standalone scripts like example1.lua from the Script Editor located in the SDK root directory.

 

and by the way, my way is better than Josh's example because it actually sets the properties dialog as well as setting the collision type.
