# Game collision dection problem

hi
this is for a university project. on line 223 I am having trouble making so the player doesn’t go over the water. I cant figure out a way for the player to not move over the water without the player getting stuck could someone please help me

character c1 = new character();
desertbackground bg = new desertbackground(750,500,1500, 1000);
wbackground w1 = new wbackground(600,200,400,200);
void setup() {
size(1500, 1000);
c1.values();
bg.varable();
frameRate(30);
}

void draw() {
background(100);

bg.display();
w1.display();
c1.move();

}
