Just a simple script; press 1 to spawn two trees in front of you then press 2 to rotate one tree.

It supposed to rotate both tree, but it's only one tree rotating (object 0@), I tried to rotate the other tree (object 20@) by using opcode 05A6 first then use 0453 to rotate it but didn't work!

So, what does opcode 05A6 use for? I thought it would get an object rotation so you can use it to set another object's rotation to be same as the one you get?

You wrote $20@. SB oddly accepts this big syntactical incongruity and treats it as a local variable with a hexadecimal identifier (32@).

I'm sorry I made mistakes when typing the script especially the $20@ I meant it 20@.

This time is the correct one. If you have time, please try it out to see what this script do.

The tree on your right is the object 20@ that won't rotating.

[12jango]

Is there any way to use 05A6:?

huh, funny should I fix that or leave it alone as a one yet feature?

Maybe tweak it so it's less ambiguous and allow hex for globals too?

[Wesser]

It is not bad at all. I would suggest to clear the ambiguity with a percent sign (%).

[fastman92]

What about

 

$0x20 - global variable with ID 320x20@ - local variable with ID 32

[Wesser]

It will be still ambiguous as x and X are valid characters for defining custom globals names. Adding a special character right after the dollar sign ($) or before the local ID will easily advert SB to treat everything following (till another distinguishing token) as a hexadecimal number.

[fastman92]

Ok, true.

[Seemann]

GTA scripts have too much data types characters already, so I would not add a one yet as the proposed percent sign.

 

The common convention for the variables naming is that the names must not begin with a digit. So $0x10 is not a valid name.

In fact SB threats it as a hexadimal value and compiles $0x10 as $16. Similarly, 0x10@ will be compiled as 16@. It means that the fastman's way is already implemented.

 

$20@ definitely should be reported as an error by the compiler (and it looks so, two data types characters in one token are used).

[Wesser]

Yes, my bad, SB behaves like most compilers do indeed. Didn't know about the way of representing variables indices in hexadecimal. I totally agree with you then.

[12jango]

So you're saying 05A6: isn't working at all?

Anyone?
