Can't get the position of CSG objects?

[nick.ace]

Whenever I try to get the position of a CSG cyclinder, the game crashes. If I replace it with another object, it runs fine.

[DerRidda]

The old "CSG geometry without either a script or mass attached gets 'collapsed' into nothingness" behavior has bit you in the arse, welcome to the club, I can still feel where it bit me.

 

Either add a mass or a script (a blank one is fine) to the CSG in question and you will be fine.

[Ma-Shell]

How are you trying to determine the position? Likely your problem is caused by the fact that all CSG gets collapsed unless they have a script attached or a mass.

[nick.ace]

Ah ok, I didn't know that. Thanks for the help! I guess this thread can be deleted then.

today i had the same problem, should be fixed, i waste hours for find the reason.

instead of crash there should be a message appear.

today i had also the problem that i can't start in debug mode...

if i call a simple command i expect it works and gave me the result.

How are you getting the CSG object in the first place?

[nick.ace]

I was parenting the CSG object to a pivot and then accessing the child of the pivot in the code.

[MarkusR]

for me i using a csg /\ as respawn point, there from GetPosition() crash the game.

i replaced it with a pivot.

[Josh]

Yeah, but how were you getting the entity in the first place? It sounds like your entity variable would be NULL.

[MarkusR]

what means?

i add a blue object from toolbar into the scene.

i drag the object from scene view into a player entity property var.

inside player script i call a function Respawn, there i test if the spawn point object is set

and want get his position.

replaced with a pivot works.

 

-- drag from scene tree view into this property field
Script.entityrespawnpoint = "" --entity "Respawn Point"
function Script:Respawn()--in
   if self.entityrespawnpoint ~= "" then
    self.alive=true
    self.health=self.maxHealth
    --crash!?
    local pos = self.entityrespawnpoint:GetPosition()
   end
end

@MarkusR

 

The point DerRidda was making above is that the CSG gets collapsed at runtime. Basically what this means is that it doesn't behave like an entity, but more or less part of the terrain. It then becomes inaccessible at that point.

@nick

what ever he said, i selected a object shape from toolbar and put it into scene, its looks good in editor.

i do not expect any strange behavior. its a entity it have a position, this .getposition crash my game today.

objects do not need a script, object falling down if they have a mass, my was mass 0.

i replaced it with a pivot and everything was fine then.

[nick.ace]

That's the thing though, it's not supposed to be an entity. It's actually part of a brush? (idk if I'm using the right terminology). Anyway, all of those CSG shapes aren't actually entities. You can also edit the terrain in the editor, but that's not an entity. It's just a little misleading since you can attach a script to it and do things like that, but you can't use standard entity commands.

[Josh]

Okay, so we found a new situation where brushes should be prevented from being collapsed...when they are used as a parameter in another entity's script.

[MarkusR]

@nick,

yo , must be a entity, seems Josh fixed it :-)

[Rick]

That's a great idea Josh. Would love that "don't collapse" flag as well.

[AggrorJorn]

I recall there already was an option somewhere in the appearance tab that was called something like 'Collapse'. I don't see it anymore though.
