stringing % signs and values

[Untra]

I'm trying to edit scripts for myself, and so far everything is going quite smoothly. I know very little about scripting, and I believe I have gotten quite far with my rather impressive lack of knowledge.

Heres the situation, I'm editing my menu system so that at the bottom of the menu->status you would see the players evasion. Its all set up and working, but I would like the evasion value to read as a number and a percentage sign. I figured that making a string would work, but this doesnt seem to be the case.

When adding the evasion I had to add another number in window_base for it to be called properly, so it looks like this:

    when 7
      parameter_name = "Evasion"
      parameter_value = actor.eva

This comes out fine and dandy save for that I get the straight value and not with a pretty % sign afterwords. Ive tried stringing it but it keeps yelling at me for improper syntax or something else. thoughts?

I believe this is an easy fix. Originally you were probably doing something like this:

parameter_value = actor.eva + '%'

The problem with that is you are adding a numeric and a string. And ruby doesn't automatically convert numbers to strings so it throws a nice little error. The fix is quite simple and you only need to convert the number to a string.

parameter_value = actor.eva.to_s + '%'

However I'm not really sure what you are describing entirely. So my idea might be off. Let me know if it still doesn't work.

Good luck with it Untravaersil! :thumb:

That did it! The value for evasion now has a % sign attached to it, which is exactly what I wanted. Thanks!

PS: you can also use :
parameter_value = "#{actor.eva}%"
