Simple request: Running?

[uupa99]

Im kind of a noob so sorry if this is very simple or something. I have searched aorund the forum a bit and haven't found anything. Specificaly, what I want is to have a normal speed, 3, which will be walking. No buttons pressed to active that. however, I would like it so when you hit or hold, lets say Z, the speed goes to maybe 4 and that would be like running.

Also, what would be nice, but I don't really NEED it, is also when you hit the button for running, the spirte changes to something else like lets say the same person only looking like he is running.

Can someone tell me how to do this please?

Seph was going to put this in his test bed, but I don't see it????

I'm sure this was done before, but I don't seem to be able to find either one, so....

      @move_speed=4

end

Hmm, didn't realize it was quite this simple until I tried it.

Be Well

[edit] oops, forgot the sprite change. I'll work on that then update.

Ok, here's V2, with the character set change...

Hey brew

if FileTest.exist?("Graphics/Characters/" + @character_name + "_dash.png")

That is a dangerous construct since it will fail both if the project is compressed and if the file exists in the RTP. It's mostly the former issue which is of concern.
Instead I would suggest trying to cache the character since that can retrieve the graphics from the encrypted archive.

    begin
      # Check that the graphics for the new character name actually exists
      RPG::Cache.character(("Graphics/Characters/" + @character_name + "_dash.png"),0)
      # Change it now that we know it exists
      @character_name += "_dash"
    rescue
      # The dash graphics does not exist.
    end

*hugs*

Thanks Z, I like that better!

P.S. Cache doesn't need the path. It attaches it internally! :wink:

 

[Zeriab]

Oh yeah. I forgot. (I should have tested it >_>)
At least you got the correct idea ^^
It is not funny when something stops working after you encrypt the project.

 

[uupa99]

Thank you! These worked great!

Brew, I wouldn't suggest changing the @character_name, but the attr_reader method, character_name.

class Game_Character
  alias_method :brew_dashing_gmchr_cn, :character_name
  def character_name
    s = brew_dashing_gmchr_cn.to_s
    s += '_dash' if dashing?
    return s
  end
  def dashing?
    return @dashing
  end
end

Now where you would modify the @charcter_name, just set @dashing = true/false.

I've learned modifying instance variables can cause incompatibility errors, where modify reader methods is less dangerous.

 

[Brewmeister]

Cool. I scratched my head about leaving the @character_name alone, if for nothing else to make sure it never got set to <charname>_dash_dash
Just wasn't sure of the most efficient way to do it.
Thanks

Oh, I have a question for something a bit more elaborate. My game switches back and forth between sprites, depending on what area you are going through, sideview or overhead.

Spoiler

Can I make it so the script is like, disabled or something when a transition is made between maps so he can't run at certain points? It would greatly reduce the amount of sprite work I'd have to do.
