getNodeByName in Material editor

[Alireza.khoshpayam]

Hi!
I want the nodes that have a specific name, for example "fall_map", to be identified and to be able to change their information, for example, to change the front color of that map.
I have no idea, I would appreciate it if anyone could help me!

I'd start reading these:

Thank you Istan but none of the links work for me

I just checked: they work. AD probably locked you out.. where are you located?

[Alireza.khoshpayam]

Iran!
I agree with you, probably the reason is the same 😞

But you have access to this board.. fascinating..

You're asking how to find the Slate Material Editor node by name... but what does it matter where it's located? The only fact that this node exists makes sense.

So, it doesn't matter where we look for the node...

Because you want to change a specific node setting, this means you know the class of the node.

Let's find all instances of this class and check that the name matches:

fn findInstanceByName name class:FallOff = 
(
	instances = getclassinstances class
	node = undefined 
	for i in instances where (stricmp i.name name == 0) do exit with (node = i)
	node
)

/*** Usage:
findInstanceByName #fall_map class:FallOff
***/

to compare names, we use the stricmp method, which is case-insensitive and can take either a string or a name type argument.

Thank you Denis! That's exactly what I wanted.
Can we change this code a bit?
to get only the nodes related to the object we selected and have this name, not all the maps with this name.

[denisT.MaxDoctor]

fn findInstanceByName name class:FallOff target: = 
(
	/* the target optional argument must be a valid object or unsupplied */
	-- if not isvalidobj target do target = unsupplied

	instances = getclassinstances class target:target
	node = undefined 
	for i in instances where (stricmp i.name name == 0) do exit with (node = i)
	node
)

/*** Usage:
findInstanceByName #fall_map class:FallOff target:selection[1]
***/

Try to figure out how the code works... MSX's help is enough for that.
Don't use someone else's code without understanding.

Thank you a lot Denis!
