Feature requests / batch draw

« on: July 18, 2019, 02:32:39 am »

Pyglet's batch draw different sprites without sfml fast
But pyglet's batch draw the same sprite (each sprite has the same texture) much faster than sfml's draw(sprite)... such as batch draw 10000 sprites.

Can you add a batch draw of the same texture sprite in sfml later? This is  faster, on some occasions


#pysmfl example:  not full,but you can use c++ sfml to test the speed of draw 10000 same sprite

windowStyle=sf.Style.DEFAULT

if 1:
    window = sf.RenderWindow(sf.VideoMode(640, 480),
                             'Drawing an image with SFML',windowStyle)

#sf.Style.NONE
    window.vertical_synchronization = True

    window.framerate_limit = 60

    window.key_repeat_enabled=False
   
    running = True
    #texture = sf.Texture.from_file('zblow3.png')
   
    ls=list()

    png=pngList[0]
    texture = sf.Texture.from_file(png)
    texture.smooth=True
    for i in xrange(10000):
        #png=choice(pngList)
        #png=pngList[0]
        #texture = sf.Texture.from_file(png)
        #texture.smooth=True
        sprite = sf.Sprite(texture)
        x=randint(0,640)
        y=randint(0,480)
        sprite.position=x,y
        sprite.rotation=randint(1,360)
        ls.append(sprite)

... ...
        t1=time.clock()
        for s in ls:
            #x=randint(0,640)
            #y=randint(0,480)
            #s.position=x,y
            #s.rotation=x
            window.draw(s)
            pass
        #window.draw(sprite)
        t2=time.clock()
        print 'cost is',t2-t1

Python / Re: Can't install PySFML

« on: July 11, 2019, 12:29:20 pm »

you can donwload some example to start learn pysfml... it is easy to test it out...


and there are some small broken in examples.... like the pong.py example

you need to change
        if event == sf.Event.CLOSED:
            window.close()

to
        # close window : exit
        if type(event) is sf.CloseEvent:
            window.close()

and change
       event['code'] 
to
       event.code


change import sfml as sf    to  from sfml import sf 

then it can be a workable example...

it is hard to compile it from sources...

pip install pysfml  dont work now

the besst way is that down the wheel and   pip install xxx.wheel yourself

« on: July 11, 2019, 12:22:03 pm »

nice work...

i tried to in stall pysfml with gcc + setup.py .... ... ends with some ld error... ....

pysfml is great... it is faster than pyglet in many sections... but it is hard to install.... ...

the best way to install is that download a pysfml.wheel then pip install wheel...

pysfml wheel download

Python / Re: Back and working on restoring pysfml

« on: July 10, 2019, 07:31:58 pm »

i have been work with pyglet about some years...

pymunk+pyglet is a good idea... ...   but when your game have more than 200
dynamic sprites which move with pymunk, pyglet will get a little even too much slow......   so i have been going to find a faster python's game engine

def testSpriteUpdate():
    t1=time.clock()
    for body in logols:
        sprite.rotation = math.degrees(body.angle)
        #sprite.rotation = body.angle
        sprite.position=body.position
        #sprite.set_position(*body.position) #slower than sprite.position=x.x
        #a=math.degrees(body.angle)
        #b=body.angle   #cost time without the #lines....
        #sprite.x,sprite.y=body.position
    t2=time.clock()
    print len(logols),t2-t1

logols is a list with 200 pymunk's body... ...
it will take about 0.012s ..... ...with nuitka pyglet's sprite.py to sprite.pyd ,it will still cost 0.009s in my computer  it will be hard to keep frames in 100 when there are more than 200 sprites or animation on a same screen


but... ...when i tried out pysfml about 1.5 day , it is quick a lot than pyglet... ...

pymunk+pysfml is better than pymunk+pyglet.... (i dont want the pygame it is not so pythonic)

a small tip is that rotated sprite in pysfml... ...set texture.smooth=True, it will be beautiful as same as pyglet

pysfml is soooo good to use.... python and c++ speed... ...

pyglet has a animation class, and pysfml can get one by myself etc...



pyglet and pysfml is similar,,,, and pysfml is a lot faster than pyglet in many sections....
pyglet is pure python code... ...

pyglet has a batch.draw .... a lot of sprite can be added to a batch...
but when the sprites come from different image it still cost more time than for i in spritelist: window.draw(i) with pysfml...  pysfml is a lot faster than pyglet when sprites with different textures

when lots of sprites come from a same image... batch.draw can faster a  lot than pysfml's draw i for i in list...

.... ....

pysfml is great... ...
