Display TExt + custom text

mrpacogp

I dont remember how to use display text, display a attrib and add custom text like: score.."game.score"
im using search for the forum..

Hi @mrpacogp Simply drag out a Display Text behaviour, then click the "e" symbol for the expression editor.

As far as I can see, you've used the quote marks for the attribute and not the word; should be:

"score "..game.score

To put the space after the word score, hold down option (alt) and hit the spacebar.

With Game score works, but not with bolean like true or false
With "score"..game.score shows Score0
No problem with space feels better (could be this added to the cookbook?)
Whats about bolean attribs?
dont work display text: "Attack "..game.attack (invalid expression9

Booleans are fine to display as well; you'll either get false or true, depending on their state.

So for your example "Attack "..game.attack, providing game.attack is a boolean, it should display either Attack false or Attack true. The invalid expression message means something's not been put in correctly...not sure what... (maybe you typed in the attribute rather than selecting it).

I put "Something "..game.attack
and only get invalid expression
I have destroyed the actor and recreate it and still invalid
Dont work, i have tested on a blank project and maybe is another formula.

Im testing all way to make it work with bolean attrib...
game.score.." score" works too :P

Hey @mrpacogp I see what you mean.... that is totally unexpected, and should work with booleans as well.... just the attribute on its own shows fine, but concatenated with a word doesn't seem to... I'll investigate further... (but surely must be a bug...)

mrpacogp

I think is a bug.
In debugging statement its the same issue:
Log statement: "score "..game.score
and you see: Score 0
Log statement: "rule "..game.rule
and you see: Invalid Expression

Its a bug?

Just tested, and works with integer, real, index, angle.... but never with boolean!!!!!

I think you're right, it has to be a bug... well spotted... worth contacting support about, I think.

Nope, you cannot concatenate anything with a boolean. The ONLY DisplayText expression that will work with a boolean is the boolean attribute itself. I added this as a feature suggestion recently.

@mrpacogp

Make a text attribute and say when boolean is true, change to true and when boolean is false change to false and then display that text attribute

This way, you have a text attribute thats essentailly mimicing the boolean, but is also displaying via display text.

And if you're trying to chain booleans together, then make an integer attribute that x%2, then if its 1 its odd, and if its 2, its even.

Hope I'm not mixed up, but I think this is what you want

@Chakku, very good idea!!
