[Resolved] Image Rotation with Alternate axis?

[shintashi]

Say I have a picture and I want it to rotate about a portion that isn't its center or 0,0 coordinate. How would I do that? In flash I just double click inside the movie clip and move the image so the 'center' of gravity is where ever I want it, but in Ruby, I have no clue.

[shintashi]

supposedly this centers stuff "sprite.ox = sprite.bitmap.width / 2, sprite.oy = sprite.bitmap.height / 2. "

and something like angle (out of 360) sets rotation. I'll have to do some testing soon, after I find a direct line of code for rotation.

[cozziekuns]

Yeah, just change the ox and oy values.

[shintashi]

Yeah, just change the ox and oy values.

but there's no ox or oy values for pictures?

ok, I guess I'll try messing with it. First step is to see if I can display a picture without using eventing - via some short script...(i.e. I still don't know what I'm doing yet, but Im closer)

[cozziekuns]

You can always make your own, and then alter it using script calls:

Code Select Expand


class Game_Picture

  attr_reader   :ox
  attr_reader   :oy

  alias coz_shin_angling_gp_initialize initialize
  def initialize(*args)
    coz_shin_angling_gp_intialize(*args)
    @ox = 0
    @oy = 0
  end

end


And then alter Sprite_Picture. Finally, you can make script calls by setting pictures public and using:

Code Select Expand


$game_screen.pictures[number].ox = blah
$game_screen.pictures[number].oy = blah


[shintashi]

I see. Right now I'm trying to turn 10 images into part of a special menu. While I've got three separate parts that have to rotate, I'm worried about four things:

1. I have one image for an arrow but I need three copies on the screen (should I make two more copies?)
2. I need to properly layer these images, and I'm hoping I can personally set each z coordinate
3. I forsee the instant/always on problem coming
4. I need to be able to dispose of all these images


to give you an idea, this is about as far as my image programming goes:

Code Select Expand


@sprite = Sprite.new
@sprite.z, @sprite.x, @sprite.y =
120, 160, 0

@sprite.bitmap =
RPG::Cache.picture ("arrows")


and that's largely a rip off of something I programmed last year while learning from a tutorial.

[shintashi]

Code Select Expand


@sprite = Sprite.new
@sprite.z, @sprite.x, @sprite.y =
120, 160, 200
@sprite.angle = 40
@sprite.bitmap =
RPG::Cache.picture ("arrowR")

p @sprite.rotate_speed


Everything works except the last line...I tried @sprite.rotate_speed = 1, but it crashed. Apparently even though rotate_speed exists, it can't be accessed or is thought to exist.

[cozziekuns]

Game_Picture is totally independant of Cache.picture. Look up the sprite class instead.

[modern algebra]

@rotate_speed does not exist in the Sprite class. It exists in the Game_Picture class, because this is how that class handles rotation in the update method:

Code Select Expand


    if @rotate_speed != 0
      @angle += @rotate_speed / 2.0
      while @angle < 0
        @angle += 360
      end
      @angle %= 360
    end


To rotate a sprite like in your example, you need to change the angle directly, and that will require frame updating.

[shintashi]

I was afraid of that.

can a frame update fit inside the little eventing script editor?

I'm guessing not:

Code Select Expand


@sprite = Sprite.new
@sprite.z, @sprite.x, @sprite.y =
120, 160, 200
@sprite.angle = 40
@sprite.bitmap =
RPG::Cache.picture ("arrowR")
ab = Graphics.frame_count
bb = Graphics.frame_rate
if ab / bb != @total_sec
@sprite.angle += 1
end


was all I could fit in there and the last lines didn't seem to work. I also noticed if I load more than one image - even ones with different depth and names, the computer makes all but the last disappear, but when stacked on top of each other they get 'thicker' and then "thin out' like they are loading on top of each other then vanishing. I'm hoping there's a way around that and I think it has something to do with update and refresh. Clearly this is going to be a whole new Class.

[modern algebra]

It would certainly be possible, though unwise. Why are you restricting yourself to events?

In any case, one way to do it would be to make the sprite a local instance variable, and then you could have a parallel process where you just perform the update.

But it's not a smart way to do it. You're making this way harder for yourself than it has any reason to be. You could just add the ox and oy attributes to Game_Picture and add something to Sprite Picture to mirror those attributes, and then you could do almost everything through the default event commands for controlling pictures. All you'd need to do through the script event command is set the ox and oy to whatever you want it to be.

My goal is to make a new menu that will appear during battle, made up of 12 separate images.
3 images will rotate on command
3 images will move left or right
6 images are stationary

the layer depth is also important. I just wanted to test the most basic functions using event script, to see if I could do each of the functions. Right now i can't adjust my center of gravity  until i can get an object to rotate. I thought it would be faster to get the ox oy corrections through a small event script.

[shintashi]

well i got 11 of the 12 images uploaded through Scene Battle, and now I have try to rotate some of them and correct for ox and oy, which I have like, no clue how to do... wish me luck

[LoganF]

Whilst it is a solution, I'm not sure how efficient it is. Also, graphical things are something I've only just started getting into so my knowledge around the Sprite related classes is limited.

Made simply by following Cozzie's method he first put up and modern's always useful advice on having Sprite_Picture reflect those new parameters.

Sprite_Picture normally sets the ox and oy (Sprites already have this parameter) based on the origin option selected in the Show Picture command. 0 is Top Left and any other value (it uses 1 but it's irrelevant) sets the ox and oy to the centre of the bitmap/sprite. I had to change the way the update is handled, so that 1 is now always centre origin, and any other value is the ox and oy value of the Picture itself.

All you need to do is set the ox and oy values via the script command:

Code Select Expand


screen.pictures[n].ox = blah
screen.pictures[n].oy = blah


This also points out a small mistake in Cozzie's snippets.

$game_screen isn't defined as such, but Game_Interpreter has a method called screen that acts as the same thing*. Also, ox and oy need to be accessors or writers to allow writing to it. Reader won't work but he already knows that I'm sure.

There's probably a better way around this but it should do.

*Random info: There's two kinds of screens; $game_map.screen and $game_troop.screen. You could access the pictures shown on the map via $game_map.screen.pictures[n] but it's unnecessary since Game_Interpreter does that for you. Same for $game_troop.screen for pictures shown in battles. Useful to know... perhaps.

I have yet to figure out how to dispose of the images once displayed, but I at least figured out how to keep all but the last image from vanishing - by creating 'sprite1,sprite2...spriteN" instead of "sprite".

some of the problems I'm experiencing:
it reads all the button pushing simultaneously - so as soon as I select the "strategy" and load these options, it also reads the

Code Select Expand


    if Input.trigger?(Input::C)
      $game_system.se_play($data_system.decision_se)
      make_strategy_result
    end


which then immediately loads the "phase3_next_actor" and '@sprite.dispose'.

finally, The arrow keys UP/DOWN/LEFT/RIGHT are still being used by Command menu instead of my script.

ok, so i haven't figured out how to access the arrow keys yet, but I've got the idea on the spacebar to open the program also activating itself.

Basically, everything is running at once, and then stops. I think I need some kind of for loop. All this has to be done before I can test the image rotation.

Basically, the idea is by pushing the left or right keys, one of the objects on the screen rotates, while another moves left or right, and a sound plays acknowledging a button has been pushed.

Unfortunately, when I push the buttons, nothing happens. Neither Rotation nor Movement along the X axis.

[shintashi]

ok, so i think the problem im running into is based on the interface of the Window_Selectable update section of arrow keys.

I want to use arrow keys somewhat similar to the shop structure, without worrying about index values, but it seems like it wants a window to base my loops on.
