So, I guess I've hit a roadblock with programming.

I used to dabble with coding back in high school, I've always been interested in writing programs etc... But I really started to learn with Ruby, first as a means to write RMXP scripts and then just to learn the language. Then, I switched over to C++ (which I was familiar with) and started to re-learn the fundamentals. Everybody says that it's difficult to go from a dynamic language to C++, but I'm not having a hard time with it. So, I'm in this class right now (Object Oriented Design in C++, has nothing to do with my major) that I tested into and it's interesting. It's it's fun to code stacks and make linked lists and delve into the technical details, but I need a practical project that I can work on.

Writing an emulator has been on my mind for a while, but I don't even know where to begin...

Kind of a broad topic I understand if nobody has anything for me. Any ideas?

so, I thought that I had a good grasp on aliasing, but then I started thinking about it a little more and confused myself...

example: a basic HUD alias

class Scene_Map
  alias mainHUD_main main
  alias mainHUD_update update
  
  def main
    @window_HUD = Window_HUDMain.new
    mainHUD_main
    @window_HUD.dispose
  end
  def update
    @window_HUD.update
    mainHUD_update
  end
end

so, what is the deal with the aliased method placement? It usually works out for me in the long run, because I can just switch them around if anything is acting up... but what exactly is going on here? Is it that @window_HUD has to be defined before the main method is called so it can be disposed? But if thats the case, why is update above mainHUD_update?

[Particle Weather]

Particle Weather
Authors: GasolineWaltz
Version: 3
Type: Particle Engine for weather effects
Key Term: Environment Add-on

Introduction

As of right now, this script does two things: creates particle weather and wind effects. Both of these functions are independent, which I think makes for pretty good control over the environment in your game.  

Makes use of particles in the Graphics/Pictures/Particles folder

here's some particles http://www.mediafire.com/?f4dl7aj8zfmml7m

Features

• Weather Particles


• Wind

Demo

http://www.youtube.com/watch?v=FsA9ycYqGyM

this is just to give you an idea... the screen cap software I used only records at 30fps, and makes the game seem a little choppy.. It looks soooo much better in game. Especially the rain, you can't really see the wind effects in the video cos of the low fps.

here's a very simple demonstration of the particles at w3rk

https://docs.google.com/leaf?id=0B5AnMItZ28l8N2Y3Y2Y0ZTktZTBmYS00MTY0LTg5OGYtMzczYjEyZWU5NDI3&hl=en


Instructions
Two things:

$game_map.p_weather(type, power, duration)
       type:     enter as a string. ex: 'rain'
       power:    number of particles to appear on screen,
       duration: amount of time in frames weather takes to reach its max (buggy)

$game_map.p_wind(strength, duration, direction)
      strength:   enter as an array: [x power, ypower] (as of right now this number has to be a multiple of four)        
      duration:   amount of frames between gusts
      direction:  enter as array w/ numbers:
                   [4= left; 6 = right, 2 = down; 6 = up]
                          note: x may be reversed... just mess around with it

#particle_struct at line 214 is h youow build new particles, I tried my best to lay them out in a readable fashion... it's pretty self explanatory, just make a new 'type' and then give that type a bunch of features.


Additional notes:

 If you like this script, help out! It's still in its initial phase, I'm sure there are some bugs to work out... but that aside, more particles/new more realistic particles, effects etc... it could be a pretty cool thing

Compatibility
 Seeing as this script just aliases #game_screen and #spriteset_map, it should work with most scripts...

[Run / Dash / Jump]

Run / Dash / Jump
Authors: GasolineWaltz
Version: 1.0
Type: Run and Jump System
Key Term: Custom Movement System

Introduction

This script started as part of a bigger project from a game that I'm working on, but it was getting too big and I decided to break it up for the moment. Basically, this provides the ability to run while pressing the A key, and jump when pressing the S key. For the first few seconds while running, the character is 'dashing' and can bump into things. Also, you can jump one more tile while dashing. The jump feature can be disabled with terrain tag #2.

I'm still kind of new to scripting so I wanted to get some opinions, I'd like to make it better... such as disabling jump when a message box is present but I'm not exactly sure how to do it. any feedback would be appreciated.

Features

• use the "A" and "S" keys to run and jump
  
• use terrain tags to make walls
  
• script calls for many useful functions
  
• <AND SO ON>

#Run/Dash/Jump by GasolineWaltz
#=================================================
#This script allows you to dash, run and jump by pressing
#  the 'A' and 'S' keys. You can also have events interect
#  while dashing by calling $game_player.hit_wall.
#
#Jump can be disabled with the terrain tag 2.
#Run or Jump can be disabled / enabled by calling
#  $game_player.toggle_act('disable/enable', 'jump/run').
#
#$game_player.run_count accesses the players run counter 
#  for status bars / event interactions
#
#$game_player.disable_jump/disable_run returns
#  the status of running of jumping.

[EDIT]
sorry about not using the template

"I would Like to thank Ryex for properly applying the template" or at least that is what I would say ~ Ryex

Whats up all? I'm coming over from RPG Revolution forums, I think I like it better here. I'm mainly down with scripting right now, still learning etc...

So, anywayz, how is everyone doing?
