Hello Everybody !

I've been testing my script,when this error popped up.Please help ! Here's the code :

Spoiler
def start super() @background_sprite = Sprite.new() @background_sprite = Cache.picture("background") @background_sprite = 0 @background_sprite = 0 @background_sprite.zoom_x = 544.0 / @background_sprite.bitmap.width @background_sprite.zoom_y = 414.0 / @background_sprite.bitmap.heightend
Thanks in Advance !

Probably

@background_sprite = 0 @background_sprite = 0What are you trying to do with those lines anyway?

Did you mean:
Code:
@background_sprite.x = 0 @background_sprite.y = 0

Creating a Sprite background.I'll try your suggestion.And thank you for your time.

Yeah, you shouldn't need to set the picture to zero, that's most likely the cause of the error since a bitmap/picture shouldn't be set to a number.

But the x and y values can be set to zero, which is what I thought you were trying to do.

I tried your suggestion,but it threw me another error :

"Script U1G Simple RPS System line 36 : NoMethodError occured

undefined method "x=" for #<Bitmap0xb7b0dbc>"

Here's the complete code if you want to check it :

change

@background_sprite = Cache.picture("background") # The image that'll serve as a backgrounto

@background_sprite.bitmap = Cache.picture("background") # The image that'll serve as a backgrounBecause you just put a picture into your sprite variable, changing the variable type.

Thank you Napoleon.I'll try that.

EDIT : IT WORKED !!! Just a issue,the def create_title method dosen't work...The scene dosen't work...

I'm not too good at scripting and you code a whole lot different than I do, so I'm not sure :p

Looks pretty complicated for one of your firsts though!

(I meant that in a good way)

when you start you class, you usually set up a initial method where you set what the class does when it starts.. usually you set some variables and things that should start up right away.. like in windows you'd draw the contents (usually by calling a refresh method).

Scenes work the same way, but instead of a initalize method they use "start". So for you scene, all you've told it to do is to create a sprite and display an image. You'll need to add methods to it. Like:
Code:
def start super() @background_sprite = Sprite.new() @background_sprite.bitmap = Cache.picture("background") # The image that'll serve as a background @background_sprite.x = 0 @background_sprite.y = 0 @background_sprite.zoom_x = 544.0 / @background_sprite.bitmap.width @background_sprite.zoom_y = 414.0 / @background_sprite.bitmap.height create_title create_commands create_window_messageend

Perhaps you should look around at some Ruby tutorials and how to get / set an object's properties (aka variables). For instance, you were calling this code:

def start super() @background_sprite = Sprite.new() @background_sprite = Cache.picture("background") @background_sprite = 0 @background_sprite = 0 @background_sprite.zoom_x = 544.0 / @background_sprite.bitmap.width @background_sprite.zoom_y = 414.0 / @background_sprite.bitmap.heightendDo you fully understand the code you just wrote, or did you write it by looking / copying from another source? Here are quite a few problems with your code:1) @background_sprite is being set to a new Sprite object, but then is set to a Bitmap object on the next line. The next two lines after that both set @background_sprite to 0. From the context, I'm assuming you were trying to set the sprite's bitmap, x, and y variables, so you need to do as Venka suggessted.

2) The line "@title = Window.help.new(1)" will throw an error; perhaps you meant: "@title = Window_Help.new(1)" ?

3) I would also recommend that you move the code that creates the background into it's own method, and call that method from the start() method.

4) All your if; elsif blocks of code are missing the end off of them, like so:

if some_condition do_stuffelsif this_other_condition do_other_stuffend # this end is required for your script to not errorI think this is why you had to add those ends on at the bottom of your script, right?5) In your rock(), paper(), and scissors() methods, don't use SceneManager.call(Scene_RPS); this is adding tons of instances of Scene_RPS to the SceneManager array of scenes, and when you call return_scene(), it'll just be Scene_RPS again, not Scene_Map.

6) Speaking of return_scene(), why is it in terminate()? I'm not sure you understand how the RPG Maker scene system works, but I would recommend that you remove it from terminate(). and add it to @window_selection, like so:
Code:
@window_selection.set_handler(:cancel, method(:return_scene))
I would also merging all of the rock(), paper(), and scissors() commands into one, like so:
Code:
@window_selection.set_handler(:ok, method(:choose_rps))def choose_rps case @window_selection.current_symbol when :rock do_rock_stuff when :paper do_paper_stuff when :scissors do_scissors_stuff endend
Does all of that make sense? Ask away if it doesn't :)
