Set bool from expression or variable

Is it possible to set a bool from an expression or from another variable, when I go set a bool I get a drop down with true and false. How can I make that bool dependent on something else or pass in a string "true" or "false" and just cast it, do i have to use an int? 0 1 to dynamically at that value?

It's not clear why you find true/false options unsuitable for a bool, but yes you can say if a variable string = the literal string "true" or "false", or you can say if a variable int = 0 or 1.

Piranha, I know what you mean about working with boolean variables, where you can't set the value with an expression, which is different from string and number types. Unless I'm missing some technique? That seems odd, but must be a design choice in Construct, maybe to reduce developer errors.

I use booleans like you describe, toggling them from within a function, for example.

If you look in Construct you cannot set a local or global bool, there is only an instance variable bool which applies to a particular object. If you are trying to pass a general bool value through a function or return a true/false then there are other ways to do it. Using the bool in conditions or actions should be enough, if you are trying to do something specifically then post exactly what you are trying to do and I can assist.
