I'm new to java and I have to do a tetris. In this class in particular, I create 2 control arrays to manage the positions of the pieces on the screen, but it is giving error. Does anyone have some time to help the newbie?
package jogo;
import java.awt.Point;
public class MapeiaTela {
int[][] tela1 = new int[12][16];
Point[][] tela2 = new Point [12][16];
int i;
int j;
int x, y;
int largura=0,altura=0;
//Point coord;
public MapeiaTela(){
for(i=0; i<12; i++){
for(j=0; j<16; j++){
tela1[i][j] = 0;
}
}
for(i=0; i<12; i++){
for(j=0; j<16; j++){
tela2[i][j].x=largura;
tela2[i][j].y=altura;
largura += 50;
}
altura +=50;
}
}
public void validar(Blocos b){
x=(int )b.x;
y= (int)b.y;
for(i=0;i<12; i++){
for(j=0; j<16; j++){
if(tela2[i][j].x == x-50 && tela2[i][j].y == y-50 ){
tela1[i][j] = 1;
}
}
}
}
}
The error is as follows:
Exception in thread "main" java.lang.NullPointerException
at jogo.MapeiaTela.<init>(MapeiaTela.java:28)
at jogo.Principal.main(Principal.java:20)
