Hey all i got a simple array here of climbers. I have to put in text on the screen who reached the top of the mountain first.

can you guys write me a block of code that searches through the array and puts what climber reached the top of the mountain first?

i also need to make a function where if the mouse presses on one of the climbers the color of that climber changes....this one is not that important though.

well here is my code and i hope you guys can help me as i will really appreciate it.

*** Press the space bar to move the characters up the mountain at various speeds and press R to reset the program

int climberCount = 5;
int ropeCount = 5;
Climber[] climbers = new Climber[climberCount];
Rope[] ropes = new Rope[ropeCount];
void setup() {
size(800, 600);
reset();
for (int i = 0; i < ropeCount; i++) {
ropes[i] = new Rope(100+150*i,100);
}
}
void draw() {
background(0);
scene();
ropes();
climbers();
}
void reset() {
for (int i = 0; i < climberCount; i++) {
climbers[i] = new Climber(75+150*i, 450, color(random(255), random(255), random(255)));
}
}
void scene() {
fill(160, 82, 45);
rect(0, 0, width, 600);
fill(0, 0, 255);
rect(0, 0, width, 100);
}
void ropes() {
for (int i = 0; i < ropeCount; i++ ) {
ropes[i].display();
}
}
void climbers() {
for (int i = 0; i < climberCount; i++ ) {
climbers[i].display();
}
}
void keyPressed() {
if (key == ' ' ) {
for (int i = 0; i < climberCount; i++) {
climbers[i].update();
}
}
if (key =='r') {
reset();
}
}
class Climber {
float xpos;
float ypos;
color c;
Climber(float tempXpos, float tempYpos, color tempC) {
xpos = tempXpos;
ypos = tempYpos;
c = tempC;
}
void display() {
fill(c);
rect(xpos, ypos, 50, 100);
}
void update() {
ypos-=random(100);
}
}
class Rope {
float xpos;
float ypos;
Rope(float tempXpos, float tempYpos) {
xpos = tempXpos;
ypos = tempYpos;
}
void display() {
fill(200,175,0);
rect(xpos,ypos,5,450);
}
void update() {
}
}

Make a function like your climbers() except that instead of calling climbers[i].display(); you check that climbers[i].ypos reaches the top. If so, you can return the current index, the index of the fastest climber.
You can also add a method to Climber to check if mouseX / mouseY is within its bounds. Thus, in mousePressed(), you loop over the climbers and if this method returns true, you can call another method to set the color of the climber.

how can i spread apart the text !!! lol

Add:

int findWinner() {
for (int i = 0; i < climberCount; i++ ) {
if (climbers[i].ypos <= goal)
return i;
}
return -1; // None found
}

Call it:

int goal = 100;
void draw() {
background(0);
scene();
ropes();
climbers();
int winner = findWinner();
if (winner >= 0)
{
fill(#992222);
textSize(48);
text("Climber " + (winner + 1) + " wins!", 50, 50);
noLoop();
}
}

Add loop(); to reset().

Re: Array Questions

It doesn't make sense to iterate on all climbers to make them iterate again on all climbers... My findWinner() function was intended to be at the same level than ropes() and climbers(), and used the ypos field directly.
Oh well, as long as it works for you...
