Hello I am having an issue with my processing code. I dont know if the png files are the problem but when i run the code, the sketch crashes!I will leave the code down here:

import processing.sound.$*$;

int numPoses $=6$; $//$ Number of poses in the sprite sheet

int poseWidth $=100$; $//$ Width of a pose in your sprite sheet

int poseHeight $=100$; $//$ Height of a pose in your sprite sheet

int spriteSheetWidth $=$ poseWidth $*$ numPoses; $//$ Total width of the sprite sheet

float x $=0$; $//$ Position of the sprite

float y $=0$;

float speed $=4$; $//$ Speed of the sprite

String$[]$ locations $=\{"$beach$.$png$",$ "school.png$",$ "landscape.png$"\}$;

PImage$[]$ imgs $=$ new PImage$[$locations$.$length$]$;

SoundFile$[]$ sounds $=$ new SoundFile$[$locations$.$length$]$; $//$ Use SoundFile class

int currentLocation $=0$;

PImage spriteSheet; $//$ Declare spriteSheet at global scope

void preload$()\{$

spriteSheet $=$ loadImage$("$pnwegg$.$png$")$; $//$ Load the sprite sheet

for $($int i $=0$; i $<$ locations.length; i$++)\{$

imgs$[$i$]=$ loadImage$($locations$[$i$])$; $//$ Load the images for each location

sounds$[$i$]=$ new SoundFile$($this$,$ locations$[$i$].$replace$(".$png$",".$mp$3"))$; $//$ Load the sound effects

$\}$

$\}$

void setup$()\{$

fullScreen$()$; $//$ Sets the window size full screen

currentLocation $=$ floor$($random$($locations$.$length$))$; $//$ Randomly chooses a starting location

$\}$

void draw$()\{$

background$(255)$; $//$ Clear the screen with a white background

image$($imgs$[$currentLocation$],0,0)$; $//$ Display the current location image

PImage currentPose $=$ spriteSheet.get$(($frameCount $\%$ numPoses$)*$ poseWidth, $0,$ poseWidth, poseHeight$)$; $//$ Extract the current pose from the sprite sheet

image$($currentPose$,$ x$,$ y$)$; $//$ Draw the current pose on top of the location image

x $+=$ speed; $//$ Moves the sprite

if $($x $>$ width$)\{//$ Check if the sprite has reached the end of the screen

sounds$[$currentLocation$].$play$()$; $//$ Play the sound effect for the current location

x $=0$; $//$ Reset the position

int nextLocation $=$ floor$($random$($locations$.$length$))$; $//$ Randomly choose the next location

while $($nextLocation $==$ currentLocation$)\{//$ Make sure the next location is different from the current

nextLocation $=$ floor$($random$($locations$.$length$))$;

$\}$

currentLocation $=$ nextLocation;
