Question - Code [Solved]real("instance id") becomes 0

[Re_hei]

I'm making an text engine working by inputting commands in the strings.
(ex: "/name[Player]Hello! My name is \c[c_red]Player!)

I'm trying moving an instance into another instance's position.
For attaching a bubble text box to an character

First, I got the character's instance id in a variable.

message = "/chr[inst_379A98D7] What a nice day."

character_id = string_copy(message, ...) => charater_id = "inst_379A98D7"

Then, I converted the string into a real number.

charater_id = real(charater_id)
[Expected] character_id = inst_379A98D7

However, the variable became 0.

[Done] character_id = 0

Whenever there is 'inst_~~' in ther variable 'charater_id', real(character_id) became 0.
I tried by changing the instance id's name, but even if there was no 'inst~', it became 0, too.

What should I do?

Wow that's pretty cool, that's going over my head though unfortunately, makes me want to learn what the heck your doing lol

Real will convert a string representing a number into a number.
But inst_379A98D7 isnt a (decimal) number,
First step is to strip off th inst_ from the front of the string.
Then, use a hexadecimal to real conversion script: http://www.gmlscripts.com/script/hex_to_dec

Also, it may be, but im not sure that the number following inst_ of the instance name in rolm editor will match the instance id of the object. Something to watch put for if you get strange results later on.

Well.. It doesn't work at all
And there are also some instance ids just like inst_7A4236ED. Maybe, I think it is not a hexadecimal problem.

I want a function finding a instance/sound/script... etc in the name of string. Like 'find_instace_id("inst_7A4236ED")'.

What part isn't working? Its very hard to help without more info.

And, just to make sure, is inst_7A4236ED something you got from the room editor?

normally, inst_7A4236ED is changed to proper number like 100045 on compile time (if used as constant). There's no inst_7A4236ED when game is running. You can easily check it by running below code:

show_debug_message(inst_7A4236ED);

and notice it in compile form. There will be a number larger than 10000 for sure.

What you need todo is:

message = "/chr[" + string(inst_379A98D7) + "] What a nice day."

Which will work as you want

Remember: all macros (previously called constants) are changed to proper string/number when compiling, so aren't existing anymore in game! (That's why they are renamed from constants to macros).

Yes, I got it from the room editor.
I solved this problem. Thank you for your help very much

Just so you know: you can rename your instances in the room editor so it makes a little more sense to read.
