Used the Xcode beta, set the target to iOS 13.3, same issue.

When I try to run the app from my iPhone's home screen, it keeps crashing. I keep getting the following error: 'Thread 1: signal SIGABRT'

Does anyone know how to fix this?

I have selected the deployment target for iOS 13.2 because in the drop down menu none were available for 13.3.1

Is there a way of selecting which modal scenes I want to dismiss while keeping other modal scenes running? This would be very helpful in game development (for example, you may have two different menus open at the same time, but you only want to close one of them).

@JonB and @cvp, thanks once again! It seems to work in the way I expected now.

It seems that scene.t uses a different time frame from time.process_time, because with the same number value, the animations appear to go at different speeds.

@JonB, I tried using scene.t and scene.dt, but I can’t get it working...

Wait it actually works, I just had the wrong indentation on the update function XD

Here’s the code:

from scene import *
import time

sprite_sheet = [
Texture('IMG_0227.png').subtexture(Rect(0,0,0.25,1)),
Texture('IMG_0227.png').subtexture(Rect(0.25,0,0.25,1)),
Texture('IMG_0227.png').subtexture(Rect(0.5,0,0.25,1)),
Texture('IMG_0227.png').subtexture(Rect(0.75,0,.25,1)),
]

class MyScene (Scene):
	def setup(self):
		self.screen="game"
		self.background_color = 'black'
		self.last_update = time.process_time()
		self.sprite = SpriteNode(sprite_sheet[0],
		scale = 1,
		position = self.size / 2,
		parent = self)
		self.add_child(self.sprite)
		self.n=0
		
	def update(self):
		#self.sprite.texture=sprite_sheet[1]
		current_time = time.process_time()
		if current_time - self.last_update > 0.05:
			self.last_update = current_time
			#modify_the_sprite
			self.sprite.texture=sprite_sheet[self.n]
			self.n=self.n+1
			if self.n > 3:
				self.n=0
run(MyScene())

Thanks a lot for your help!

@pulbrich

I tried your method, but it seems that anything I put into the update function doesn’t get used...

Here’s the updated code:

from scene import *
import time

sprite_sheet = [
Texture('IMG_0227.png').subtexture(Rect(0,0,0.25,1)),
Texture('IMG_0227.png').subtexture(Rect(0.25,0,0.25,1)),
Texture('IMG_0227.png').subtexture(Rect(0.5,0,0.25,1)),
Texture('IMG_0227.png').subtexture(Rect(0.75,0,.25,1)),
]

class MyScene (Scene):
	def setup(self):
		self.screen="game"
		self.background_color = 'black'
		self.last_update = time.process_time()
		self.sprite = SpriteNode(sprite_sheet[0],
		scale = 1,
		position = self.size / 2,
		parent = self)
		self.add_child(self.sprite)
		n=0
		
		def update(self):
			current_time = time.process_time()
			if current_time - self.last_update > 0.125:
				self.last_update = current_time
				#modify_the_sprite
				self.sprite.texture=sprite_sheet[n]
				n=n+1
run(MyScene())

@JonB, I’ve also never used Action.wait before, so I’d appreciate an example of this, thanks.

Remember, I’m still a noob here lol

@JonB, I’ve already looked at the game tutorial, where it showed how to animate a walking sequence. However, that method only works when the sprite is changing its position in pixels on the screen, so it will not work for my sprite. This is because my sprite’s position is constantly at the centre of the screen.

The effect I’m trying to achieve is basically a GIF with a customisable frame speed, which is permanently in exactly the same position at the centre of the screen.

@pulbrich, could you give an example of how to check that the correct amount of time has passed?
