Member isLocked for mesh

[Dad72]

Hi,

I want a isLocked member , but it does not exist. I would lock an object to any changes even if an object is pickable.

By locking an object, you can not change it, nor materials, nor select ...

is there a similar function or member? or could it be possible to have a work like this in Babylon? 

Thank you

Woot..That's not supported right now and unlikely to be supported in the future. Too much work. 

You can freeze the worldmatrix though

[Dad72]

how to do it: freeze the WorldMatrix? 

Thanks DK

[Dad72]

ok I found, mesh.freezeWorldMatrix(); and mesh.unfreezeWorldMatrix();

But it does not work. the object can still be select, move ... 

I'll try to hack something, then. 

[GameMonetize]

yep it only freeze the worldmatrix

maybe this would help : http://doc.babylonjs.com/classes/2.3/AbstractMesh#ispickable-boolean

I know isPickable Jerome, I use it for 3 years now, this is one of the first thing I learned from Babylon. I just wish that even if isPickable is true, it may not be selectable, or modify the materials and other level.
Basically, I want to lock an object of any changes to my editor. because all the objects are selectable.
IsPickable also do not want the change on materials. isPickable is not a verous on objects. I must keep my pickable objects

If users want avoid select an object or change by error, I wish he could add a Security locks that blocks any modification, selection, movement.

Have you tried Object.freeze(obj) ?

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/freeze

I just tried it on Object.freeze(mesh.position) and it worked.  I'm thinking you could easily create a function that freezes just the properties you want to freeze.

[Dad72]

I'll try that. Thank you Adam.

[Dad72]

This works Adam. Object.freeze freezes perfectly the object. But I do not track unfreeze function to unlock.

An idea to unlock?

[adam]

I would try replacing the object with a new one.  

mesh.position = new BABYLON.Vector3(mesh.position.x, mesh.position.y, mesh.position.z);

That didn't work. 

It actually does work.  I had a bug in my code.

Ok, so we have to recreate new property if I understand well. but if I freeze the whole object: Object.freeze (mesh).

Is what I should freeze or a specific property?

[adam]

I would just freeze specific properties.

Thank you for your help bring here. Here's what I did in the end if it can be useful to the other. I hope that Babylon soon get this kind of functionality. but in the meantime, I hope this can help.

I managed to block the entire object and unlock it. In made, I simply create a clone of the subject and I add it visibility is false. This new object will be rendered visible when I unlock the freeze objects. The object freeze  will be deleted then.

This works well in 2 directions.

	lockObjet = function()
	{
		if(global.objetSelected) {	
			var name = global.objetSelected.name;
			global.objectsFreeze[name] = global.objetSelected.clone(name);
			global.objectsFreeze[name].visibility = false;
			Object.freeze(global.objetSelected);						
		}
	};	
	
	unlockObjet = function()
	{
		for(var i = 0; i < global.objets.length; i++) {	
			if(global.objectsFreeze[global.objets.name]) {
				global.objectsFreeze[global.objets.name].visibility = true;
				global.objets.dispose();	
				global.objets = global.objectsFreeze[global.objets.name];
			}
		}		
	};

 

global.objetSelected corresponds to all my global variables contained in a json: var global = {objetSelected : null, objets: [], objectFreeze: [], othervariable: valueDefaut};
