could anyone tell me where i am going wrong?
The problem is that i want to shoot a bullet thats initial direction will follow the where the mouse INITIALLY was compared to location of character on mouseclick. but my code now on mouseclick will draw another bullet(not shown here), but all bullets drawn will travel in a direction following an angle respective to current character location.
this is an example of what it looks like
int bulletTotal = 5;
float bulletX = new float [bulletTotal];
float bulletY = new float [bulletTotal];
int shots;
float bulletSpeed;
float angle;
int charaStartX, charaStartY;
int charaWid, charaHght;
int sx, sy;
boolean isUp, isDown, isLeft, isRight;
void setup()
{
size(1500,900);
charaStartX = width/2;
charaStartY = height/2;
charaWid = charaHght = 75;
sx = sy = 4;
for(int j =0; j < bulletTotal; j++)
{
bulletX[j] = charaStartX;
bulletY[j] = charaStartY;
}
bulletSpeed = 5;
isUp = false;
isDown = false;
isLeft = false;
isRight = false;
}
void draw()
{
ellipse(charaStartX, charaStartY, charaWid, charaHght);
for(int j = 0; j < bulletTotal; j++)
{
rect(bulletX[j], bulletY[j], 25, 25);
movement();
angle = atan2(mouseY - charaStartY, mouseX - charaStartX);
bulletX[j] += bulletSpeed * cos(angle);
bulletY[j] += bulletSpeed * sin(angle);
}
}
void movement()
{
if(isUp == true)
{
charaStartY = charaStartY - sy;
}else if(isDown == true)
{
charaStartY = charaStartY + sy;
}
if(isLeft == true)
{
charaStartX = charaStartX - sx;
}else if (isRight == true)
{
charaStartX = charaStartX + sx;
}
}
void keyPressed()
{
if(key == 'w'||key == 'W')
{
isUp = true;
}
if(key == 's'||key == 'S')
{
isDown = true;
}
if(key == 'a'||key == 'A')
{
isLeft = true;
}
if(key =='d'||key == 'D')
{
isRight = true;
}
}
void keyReleased()
{

Please post your code in the form of a Minimal, Complete, and Verifiable example directly in your post. That means do not post your full project, and do not post links to other sites. Narrow your problem down to an example program that focuses on the problem in as few lines as possible, and include that code directly in your post. Good luck.

ok i m not using classes anymore. way above my league. now i want to draw enemies using an array. i loaded 5 enemies into my array. but i want to draw more enemies and each enemy is a random of these 5. how do i do so?

also i want enemies to come in from top, bottom, left and right sides of the screen but my code says || operator is undefined for what i m doing. void drawEnemy() { for(int i = 0; i<5; i++) { image(enemy[type], enemyX[i], enemyY[i], charaWid, charaHght); enemyX[i] = int(random(-charaWid, 0))||int(random(width, width+charaWid)); enemyY[i] = int(random(-charaHght, 0))||int(random(height, height+charaHght)); } }
