How to have a menu with internal integer values?

[magneto]

Hi,

In my custom OP, I am trying to create a named menu with items "Positive", "Negative" and provide values like 1, and -1, respectively. I tried using an Integer item in the parameters tab of the Edit Operator Type properties dialog, with a defined menu and tokens with 1 and -1, but when I use it in the expressions, it doesn't work.

If I turn it into a float, it works but then I lose the menu.

Here is a simple case that shows the problem. The line's distance is multiplied by my menu item value but it seems the value I get from the menu is the order of them (index), instead of my tokens.

Any ideas?

Thanks.

quick fix would be if(ch("../sign")==0, -1, 1)

Thanks tmdag, I now know how to use ifs inside expressions. But would also be cool if this is doable without an if.

Am I misinterpreting the tokens? I thought they can be any value you want, when you access the parameter.

change your parameter to ordered menu and try eval as string `chs("../sign")` or hou.parm("../sign").evalAsString()

Thanks tmdag, just tried it to chs("../sign") after changing it to an ordered menu, but same result. Didn't try hou.parm but I assume it does the same thing?

Thanks man, appreciate it. I wouldn't be able to open it at work anyway

Hi tmdag, just tried your method and it works. Sorry in the example it was in the divisions field which cannot be negative that's why I didn't see it.

But it was chs and the ordered menu like you said that did it.
