How do I add textures to sprites?

heyguy4

I have a sprite called spriteName. Whenever I type something like.

self.spriteName.texture = ('plc:Gem_Blue')

or import my own image into my own folder called Textures and use

self.spriteName.texture = ('Textures/IMG_0469.JPG')

They both result in the error "TypeError: Expected a Texture Object"
I don't know what I'm doing wrong.

A TypeError usually gives you a hint that you are using the wrong type, and the message often gives details of what was expected instead. The error gives you a hint that texture is not a string, but instead a Texture object... in this case, a scene.Texture object. See the docs on creating such an object --

self.spriteName.texture= scene.Texture('plc:Gem_Blue')

should do the trick.

It might be a little confusing, because the SpriteNode() constructor's texture argument does allow a string, so you migtpht think the texture attribute is the same as what you passed in.

heyguy4

Now it says "global name 'scene' is not defined"

@heyguy4 Just use Texture instead of scene.Texture. Most included examples import everything from the scene module (using from scene import *), but not the module itself. @JonB's code would be correct when you import just the module (import scene).

Okay now there's no error, but I can't see the sprite when the code compiles.
Here's my setup method

        def setup(self):
                self.background_color = 'green'

                self.spriteName = SpriteNode()


                self.spriteName.anchor_point = (5,5)
                self.spriteName.position = (50, 50)

                self.spriteName.texture = Texture('plc:Gem_Blue')

You haven't added the sprite to the scene. You have to add something like self.add_child(self.spriteName). Alternatively, you could also pass parent=self to the SpriteNode initializer.

heyguy4

That solves the issue with the blue gem not appearing, but if I use one of my own images that I imported into the folder

self.spriteName.texture = Texture('IMG_0469.JPG')

returns a "Image not found" error and

self.spriteName.texture = Texture(ui.Image.named('IMG_0469.JPG'))

returns a "Could not load image" error

omz

Is the imported image in the same folder as your script?

heyguy4

Yes it is

heyguy4

@omz Does the folder have to have the same name as the program?

omz

No, that's not necessary, but the image shouldn't be in a sub-folder (or you'd need to include the sub-folder's name in the image name).

heyguy4

It's not in a sub folder. I have no idea why it's not working.

Try...

import os
print(os.listdir(os.curdir))  # see if 'IMG_0469.JPG' is in that list

brumm

from scene import *

class MyScene (Scene):
    def setup(self):
        self.background_color = 'green'

        self.spriteName = SpriteNode()

        self.spriteName.position = self.size / 2      
 
        self.spriteName.texture = Texture('plc:Gem_Blue')
        #self.spriteName.texture = Texture('canvas.png')
        #self.spriteName.texture = Texture('image000.jpg')
        self.add_child(self.spriteName)

run(MyScene())

@heyguy4
Try adding

import os
print(os.path.abspath(os.curdir))
print(os.listdir('.'))

at the start of your script. Then, copy and paste the name of the image that gets printed to the console. A common problem is that this is case sensitive, you must type the name exactly as it is printed.

heyguy4

I did what you said but I'm still getting the "Image Not Found" Error

ccc

What was printed when you added @JonB and/or my code?!?

Does adding the following code print True or False?!?

import os
print('IMG_0469.JPG' in os.listdir(os.curdir))
