Int To Pimage错误

Question

我试图为我的Java文档制作过滤器。

这是我的代码，但它不起作用。不要介意m4 == 1，ak == 1，awp == 1.

PImage weapon1;
PImage weapon2;
PImage weapon3;
PImage billed;
int weapon;
int m4 = 0;
int ak = 0;
int awp = 1;
void setup() {
  weapon1 = loadImage("dayz.jpg");
  weapon2 = loadImage("ak47.jpg");
  weapon3 = loadImage("295020.jpg");
  billed = loadImage("dayz.jpg");

它是执行错误的int武器，但我需要使用int武器让我的代码像我想的那样工作。

void pixel2(){
  if(m4 == 1){
  weapon = weapon1;
  }
  else if(ak == 1){
  weapon = weapon2;
  }
  else if(awp == 1){
  weapon = weapon3;
  }
  for(int y = 0; y < weapon.height; y = y+3){
    for(int x = 0; x < weapon.width; x = x+3){
      color pilex1 = weapon.get(x, y);
      strokeWeight(1);
      stroke(1);
      fill(pilex1);
      rect(x,y,3,3);
    }
  }
  }

答案：

if(m4 == 1){ 
weapon = loadImage("295020.jpg"); } 
else if(ak == 1){ 
weapon = loadImage("ak47.jpg"); } 
else if(awp == 1){ 
weapon = loadImage("dayz.jpg"); }

Answer 1

int weapon;应为PImage weapon;。 PImage billed;并没有被使用。
