So, I'm trying to animate some pixels moving around a static image using FuncAnimation. The static image itself is 256x256 and the objects moving around are essentially a brightly colored pixel. In the end i'd like for the animation to go indefinitely or until I stop it but thats besides the point. Right now I'd like to get things moving first.
The static image in question is this one (for this example anyways).
The code below is a simple class consisting of a location and color. When i spawn it or move it i make sure to record the previous pixel color so the object doesnt leave 'tracks' sort of speak.
class Prey:
def __init__(self, color = [255, 0, 255]) -> None:
self.color = color
self.x = None
self.y = None
def set_spawn(self, world):
self.x = random.randint(0, 256)
self.y = random.randint(0, 256)
while np.array_equal(world[self.x][self.y], [65, 105, 225]):
self.x = random.randint(0, 256)
self.y = random.randint(0, 256)
prev_pix = world[self.x, self.y]
return prev_pix
def move(self, world, x, y):
if not np.array_equal(world[x][y], [65, 105, 225]):
prev_pix = ((self.x, self.y), world[x][y])
self.x = x
self.y = y
return prev_pix
And below here I actually try to animate the damn thing.
def load_map(wname):
bgr_world = cv2.imread(wname)
rgb_world = cv2.cvtColor(bgr_world, cv2.COLOR_BGR2RGB)
return rgb_world
world = load_map('m3.png')
fig = plt.figure('lifesim')
im = plt.imshow(world, animated=True)
p1 = Prey()
def movement(*args):
x1, y1, prev_pix1 = p1.move(world, p1.x+1, p1.y) #i'm trying to get it to move down (when it actually works ill make sure it doesnt go OOB)
ppxy, pp = prev_pix1
ppx, ppy = ppxy
world[ppx][ppy] = pp
world[x1][y1] = p1.color
im.set_array(world)
return world,
def init_game(world):
x0, y0, prev_pix0 = p1.set_spawn(world) #The spawn is random, so i just overwrote it here so i can test
prev_pix0 = world[110, 100]
x0, y0 = (110, 100)
p1.x = 110
p1.y = 100
world[x0][y0] = p1.color
ani = animation.FuncAnimation(fig, movement, blit=True)
plt.show()
def main():
init_game(world)
if __name__ == "__main__":
main()
And when the code gets eventually executed, i get the following error

I'm not sure what I'm doing wrong here since I'm completely new to matplotlibs animation modules... The mistake is probably blisteringly obvious but I just can't see it.

I'm trying to animate a piece of text in matplotlib, in order to make some educational videos. However, I'm having trouble with setting text in motion.
I've tried to use FuncAnimation (as I did for animating lines), and defining the anchor of that text as a pair of moving coordinates. Here's what I've tried:
def data_gen(): #Data generator. Gives me the anchor.
counter = 0
x0 = data_gen.x0
while counter < 1000:
counter+=1
x0-=0.09
yield x0,(1-counter*0.05)
data_gen.x0=1
def animate_text(data): #Here is where I try to tell my code to refresh
#only the coordinates of the text.
x0,y0 = data
text_sample = ax.text(x0,y0,'text here',transform=ax.transAxes,
fontsize=12, color='black',fontstyle='oblique',family='serif')
return text_sample
#animation part:
ani = animation.FuncAnimation(fig,animate_text,data_gen,blit=True,
interval=50,repeat = False)
plt.show()
However, I get this:

Does anybody know how can I solve that?
In FuncAnimation documentation you can read:
func must return an iterable of all artists that were modified or
created
"iterable" means that animate_text() has to return list or tuple with elements - even if you have only one element:
return (text_sample,)

I would appreciate if anyone can assist me with the error, without changing the matlibplot code but only the auto code. I have read through the code but did not find anything suspicious.
I ran into this error using a given equation and auto file. But if you use matplotlib 2.0 and auto07p to plot most graphs in general, you are very likely to get this error if you zoom on the graph.
I used the files as the following:
https://1drv.ms/f/s!ArJqyyCr1FQOhkITst8JdVK_mIFV
Put them in auto folder.
Run auto.
and type:
auto("couple2.auto")
Thanks.
I am facing issues with the implementation of the method animation from the class wave bellow. The animation method aims to create an animation of a wave propagation. I do not want that the animation method modify the state instance variable u of the Wave object, and because of that I am trying to create a local variable u inside the method animation. Nevertheless, I do not know how to pass the local variable u from the animation method for the animate function that is defined inside the animation method. In the way that I tried to implement, from my conception, the local variable u of the method animation should be a king of global variable for the animate method (that is defined inside the animation method). But, this assumption is cleary wrong, otherwise I would not get an error. As a complementary information the error I am getting is: UnboundLocalError: local variable 'u' referenced before assignment.
I will be glad if someone indicate to me the way for the implementation that I want.
thanks in advance

When you capture a variable with a closure in Python, you are not allowed to assign to it. If Python sees you assign to it, then it isn't allowed to be captured from the enclosing scope; it must be a new function-local variable (local to your animate function). But since you're trying to use the captured u to initialize it, you need that u's value, but in this context Python has decided that u must be local to animate, so it isn't looking at animate's enclosing scope. That's why you're getting that error.
A simple way to get around that in your case is just to define animate as
def animate(i, u=u):
...
This explicitly passes a copy of u into animate.

grid.add_widget(scatter)
else:
label = Label(text="Please Start/Load a Game")
grid.add_widget(label)
stack.add_widget(grid)
box.add_widget(stack)
Container.MapPopup.content = box
Container.MapPopup.open()
It doesn't matter what values I put in at bbox=((?,?),(?,?)) I get the error;
TypeError: 'NoneType' object is not callable
Removing the bbox and all works normally, but the image I'm housing is spilling outside of the popup box. I don't want to resize the image using scale=.
From the docs:
bbox Added in 1.0.0
Bounding box of the widget in parent space:
((x, y), (w, h))
I think my issue is that it's scatter.scatter.bbox instead of scatter.bbox due to the ScatterLayout implementing FloatLayout, and Scatter implementing ScatterLayout, or something daft like that - can anyone help?
Many thanks!
