Collider Boxes in the Editor ?

[ParaToxic]

Hello guys, I'm very bad in lua so I have a question about some collider box stuff.

 

I would like to create a entity which you can place in the editor and create a 3D box with 3 mouse clicks.

When you place it you click on the ground once and from this point a box starts to follow your mouse ( just a 2D square maybe). When you click a second time the box has then a fixed size and you can now control the height of the box with the mouse.When you have your height you click a third time and you have your own, perfect sized collider box.

 

But how I can make that with mouseclicks and soone as a object, you can just place in the Editor ??

Thanks

Well its just a first idea with 3 mouse clicks and the MouseX component for each scale axis.It also saves the cube in the userdata so you can load it if already exists.

Looks interesting. How did you do that in Editor?

 

Why are you using userdata? You can store Width, Height, Depth as "keys" for model. They will be stored as plain text in SBX, so you could change them manualy.

Well it is very bad code but it works , for my lua knowledge

Yes I could store it as keys, your right

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

function class:InitDialog(grid)
end

function class:CreateObject(model)
local object = self.super:CreateObject(model)
local object=self.super:CreateObject(model)
SetWorld(fw.transparency.world)
object.cube=CreateCube()
object.cube:SetScale(Vec3(4,4,4))
object.cube:Paint(LoadMaterial("abstract::collider.mat"))
object.axis1 = 0
object.axis2 = 0
object.axis3 = 0
object.scalex = 1
object.scaley = 1
object.scalez = 1
object.setall = 0
SetWorld(fw.main.world)
function object:Update()

self.cube:SetPosition(self.model:GetPosition())
if self.axis1 == 0 and self.axis2 == 0 and self.axis3 == 0 then
self.cube:SetScale(Vec3(self.scalex,self.scaley,MouseX()/100))
if MouseHit(1) == 1 then
self.scalez = MouseX()/100
self.axis2 = 1
self.axis1 = 1
end
end
if self.axis1 == 1 and self.axis2 == 1 and self.axis3 == 0 then
self.cube:SetScale(Vec3(MouseX()/100,self.scaley,self.scalez))
if MouseHit(1) == 1 then
self.scalex = MouseX()/100
self.axis3 = 1
end
end
if self.axis1 == 1 and self.axis2 == 1 and self.axis3 == 1 then
self.cube:SetScale(Vec3(self.scalex,MouseX()/100,self.scalez))
if MouseHit(1) == 1 then
self.scaley = MouseX()/100
self.axis1 = 0
self.userdata = self.cube
end
end
end

function object:Free()
if self.cube~=nil then
self.cube:Free()
self.cube=nil
end
self.super:Free()--Don't forget this!!
end

end

That's cool, do you mind if I use this technique for a setting sizing properties on a trigger system?

[DigitalHax]

Maybe you could use grid snap to make a gritty geometry brush editor

 

Maybe for people who can't afford LE3

Something to watch out for, if I'm not mistaken that code will run in game also. When I was doing stuff like this with my Pi scripts, I made a flag that would tell me if I'm in the editor or running the game so I could skip over editor parts when running the game.

[ParaToxic]

@Rick: Thats a good idea for that.But how can I find out that I'm running it in the editor ?

I saw that LE3 comes with a collisiontrigger script, so I will wait for that

Also it should save the properties as keys ( I mean the scale ) and load it from keys when exist, because now when I load a scene I have to resize all the collisionboxes again.

But how can I find out that I'm running it in the editor ?

 

When you run from the editor it runs a game script. I set a global var in that script to let me know if in game mode or not.

[ParaToxic]

Yes you are right, haven't thought about that :
