Make a playground from primitives as "one big object"

[Alex88]

Hello together, is it possible to make a playground from primitives in just "one big object"? I have created a prefab and attached a lua script to rotate the playground, but unfortunately it only rotate one box.

It should work if you make all objects you want to group together, to have a parent object.

So, for example, say you have an object called 'Box1', and another called 'Box2', then simply drag 'Box2' onto 'Box1' ( in the 'Scene' tab) to make it a child of 'Box1'.

 

Hope that helps?

This was my first idea too and I saved it as a prefab, but unfortunately it doesn't work as expected.

Is the script attached to your parent box , not to a child ?

 

Try saving your cubes group as a prefab and attach script to that prefab.

create a pivot as parent. all boxes are childs. rotate the pivot

 

(cant test it right now but seems legit)

[YouGroove]

I confirm the bug.

Created a pivot , putting boxes as child and attaching a script to the pivot doing that :

 

function Script:UpdatePhysics()
local window=Window:GetCurrent()

if (window:KeyDown(Key.V)) then
self.rot = self.rot + 1
self.entity:PhysicsSetRotation(0,self.rot,0.02,0.5)
--self.entity:SetRotation(self.rot,self.rot,0.02,true)
self.entity:SetColor(0,0,1)
end

end

 

unsing entity:PhysicsSetRotation : LE 3.0 crash

using entity:SetRotation nothing happens

 

Could it be a pivot or a cube as parent , it should work in both cases.

@Alex88 :

it can be frustrating to not be able to do such simple stuff using BSP, but i recommend you to simply use models instead using BLender or Sketchup programs for example.

Why not just make the ground in blender and import it?

[shadmar]

Make an empty script call it : nocollapse.lua (doesn't need to have any code in it)

 

Add the script to box2,3,4,5

 

They shouldn't collapse on run anymore and respect the parent rotation and position.

So if you rotate the parent, they should follow.

This is exactly what I have done already.

If I attached my lua script to the pivot, nothing rotates. Here is my lua script:

 

function Script:UpdateWorld()
self.entity:Turn(1 * Time:GetSpeed(), 0, 0, true)
end

 

 

I confirm the bug.

Hehe, you are absolutely right. It is frustrating to not be able to do such a simple stuff.

 

So did I found a bug in Leadwerks?

 

Why not just make the ground in blender and import it?

 

Because I was too lazy for the UV mapping.

This really works! I don't know why, but it works! Can you explain it to me?

It's csg behaviour, there is an improvement request here :

[Alex88]

Thank you very mutch!

[YouGroove]

Classic, but missing boolean BSP "MERGE" should do this easyly without any empty script tedious tasks.

Well just wait for some "cut" and "merge" BSP tools.

[DudeAwesome]

this behaviour is just confusing

I believe it's an optimization thing so it may not make sense directly, but to speed things up I think it may be needed. If CSG doesn't have a script attached to it then it's really dummy geometry that has no function but collision/visual. That's the idea anyway.
