ball dodger: first game

[Summoner123]

i knew the problem and i thought i understood it. But i had no idea how to fix it.
Thank you so much.
BTW: it shows an error when i replace gb.display.fillRect with gb.display.fillCircle. even though it changes colour.
and 1 more question how do i make a ball hollow?
and how do i make the spawn points reset.

The error occurs because you don't have changed the parameter of function, to draw o circle you need the Xposition, Yposition and the radius of circle

Code: Select all

gb.display.fillCircle(x, y, r);

in the example of my later post I used

Code: Select all

gb.display.fillCircle(player_x, player_y, player_size/2);

If you want a circle and not a fillcircle you can change the fillcircle() to drawCircle().

Change the spawn point is very easy to, just change the position of the player and anemy after all titleScreen when it be call.

Code: Select all


  gb.titleScreen(F("unamed"));
 player_x=0;            //Move the player ball to left of screen
 player_y=0;            //Move the player ball to top of screen

 ball_x=80;             //Move the enemy ball to Right of screen
 ball_y=0;               //Move the enemy ball to top of screen

thanks again .I suck at programming
now i need to just program that each time you touch the catch ball it gives you a point and i need to make it so that at 3,6,9,11,15 and so on a new killer ball comes.

i got a score
EDIT : now it resets each time you die.

Hey if you want, here's how you could do multiple balls:
1. create variables for each ball.
2. For each ball, do this:

Code: Select all

gb.display.drawBitmap(VARIABLEX, VARIABLEY, ball)

3. Move as needed.
It's pretty simple.

Thanks i will try and implement it
i don't have a variable called ball and i don't know what to put in it.

[Skyrunner65]

No, the "ball variable" is the name of the sprite you are using for the ball...

[EatMyBlitch]

im not using a sprite.
can i make the catch ball bounce of the player?
Because then you can only get 1 point per hit instead of like 4.
BTW: the code i tried to run so that another ball will spawn at 3 points does not work. I tried this if(score/3 == int); so basically it checks if score:3 is an integer. (integer means a whole number like 1,10, 100, 50, 80. But not 1.4, 3.7, 6.3.). It says it expected a primary-expression.
here's my code.

Code: Select all

#include <SPI.h>
#include <Gamebuino.h>
Gamebuino gb;

  //declare all the variables needed for the game :
int score = 0;
int catch_x = LCDWIDTH/2;
int catch_y = LCDHEIGHT/2;
int catch_vx = 3;
int catch_vy = 3;
int catch_size = 1;
int catch_r = 1;
int person_x = LCDWIDTH/3; //set the horizontal position to the middle of the screen
int person_y = LCDHEIGHT/6; //vertical position
int person_vx = 5; //horizontal velocity
int person_vy = 5; //vertical velocity
int person_size = 6; //the size of the ball in number of pixels
int ball_x = LCDWIDTH/5;
int ball_y = LCDHEIGHT/2;
int ball_vx = 2;
int ball_vy = 2;
int ball_size = 2;
int ball_r = 2;

void setup()
{
  // put your setup code here, to run once:
  gb.begin();
  gb.titleScreen(F("Ball dodger"));
   person_x=40;            //Move the player ball to middle of screen
 person_y=24;            //Move the player ball to middle of screen

 ball_x=80;             //Move the enemy ball to Right of screen
 ball_y=0;               //Move the enemy ball to top of screen
 
 catch_x=0;             //Move the catch ball to left of screen
 catch_y=40;             //Move the catch ball to top of screen

}

void loop()
{
  // put your main code here, to run repeatedly:
  if(gb.update()){
    gb.battery.show = false;
    //Check if person touched a catch ball
    if(gb.collideRectRect(person_x, person_y, person_size, person_size, catch_x, catch_y, catch_r, catch_r))

Dammit i just lost the game!!!

BTW:can somebody please provide some lines of code. So that the catch ball bounces of the player and only gives 1 point.

Nevermind did it myself

Code: Select all

    if(gb.collideRectRect(person_x, person_y, person_size, person_size, catch_x, catch_y, catch_size, catch_size))
  { gb.sound.playOK();
      //change the direction of the horizontal speed
      catch_vx = -catch_vx;
      catch_vy = -catch_vy;
    score = score + 1;}

now the only thing i need to add is that every three times you score another killer ball comes in.

[EatMyBlitch]

Will nobody help me with the new kill ball each time you get 3 points thing?
*CRIES*

Well maybe they want you to try for yourself first. After all, the best way to learn is through figuring out after long thought, and showing through example next.
