Question

我的代码，

int selection = 0;
            if(checkKey(Keyboard.KEY_Z)){
                selection++;
                System.out.println(selection);
            }
            if(checkKey(Keyboard.KEY_B)){
                selection--;
                System.out.println(selection);
            }

似乎无法正常运作。在通过键功能更改后，整数选择似乎几乎立即变回0。

围绕它的代码是相关的

int selection = 0;
            if(checkKey(Keyboard.KEY_Z)){
                selection++;
                System.out.println(selection);
            }
            else if(checkKey(Keyboard.KEY_B)){
                selection--;
                System.out.println(selection);
            }
            if(selection < 14){
                selection = 1;
            }
            if(selection == -1){
                selection = 14;
            }
            if(Toggles.clickMenu){
                if(selection == 1){
                    var8.drawStringWithShadow(Strings.textsymbol + "b<", 62, 34, 0000);
                    if(this.mc.gameSettings.Enter.isPressed()){
                        Toggles.fly = !Toggles.fly;
                    }
                }else if(selection == 2.0){
                    var8.drawStringWithShadow(Strings.textsymbol + "b<", 62, 46, 0000);
                    if(this.mc.gameSettings.Enter.isPressed()){
                        Toggles.sprint = !Toggles.sprint;
                    }
                }else if(selection == 3){
                    var8.drawStringWithShadow(Strings.textsymbol + "b<", 62, 58, 0000);
                    if(this.mc.gameSettings.Enter.isPressed()){
                        Toggles.autojump = !Toggles.autojump;
                    }
                }
            }

这是更进一步的代码：

if(Toggles.clickMenu2){
                Gui.drawRect(85, 200, 161, 0, 0xaa000000);
                var8.drawStringWithShadow("Menu2", 90, 4, 0x00ff00);
                if(Toggles.off == true){
                    var8.drawStringWithShadow(Strings.textsymbol + "bSpeedMeUp", 87, 16, 0000);
                }else{
                    var8.drawStringWithShadow(Strings.textsymbol + "bSpeedMeUp", 87, 16, 0000);

CheckKey代码：

public GuiIngame(Session p_i1103_1_, Minecraft p_i1036_1_) {
        this.session = p_i1103_1_;
        String username = p_i1103_1_.getUsername();
        keyStates = new boolean [256];
        this.mc = p_i1036_1_;
        this.persistantChatGUI = new GuiNewChat(p_i1036_1_);
        this.field_152127_m = new GuiStreamIndicator(this.mc);
    }
    public boolean checkKey(int i){
        if(mc.currentScreen != null){
            return false;
        }

        if(Keyboard.isKeyDown(i) != keyStates[i]){
            return keyStates[i] = !keyStates[i];
        }else{
            return false;
        }
    }

Answer 1

嗯，两个条件都必须返回true。第一个条件的块递增选择变量，第二个条件的块递减它。

如果您只希望输入一个条件（最多），则应使用if：

        int selection = 0;
        if(checkKey(Keyboard.KEY_Z)){
            selection++;
            System.out.println(selection);
        }
        else if(checkKey(Keyboard.KEY_B)){
            selection--;
            System.out.println(selection);
        }

Java Integer在更改后更改第二个
