How to realize infrared module control pinball game

To write a pinball game using Verilog on Basys3, you should first define the state of the pinball game, such as whether the player is moving, whether the ball is moving, how the game is progressing, how scores are being scored, etc. Then, the corresponding function modules are defined, such as moving module, ball module, scoring module, etc. Finally, these functional modules are connected together to form an implementable Verilog circuit.

Here is the simplest pinball Verilog circuit:

//数字信号定义
wire [7:0] Xpos, Ypos; //球的X,Y坐标
wire [7:0] Hpos;     //移动板的位置
reg    [3:0] Score;     //得分
reg [7:0] Cnt;         //计时器

//移动板模块
module move (Hpos);
    input[7:0] Hpos;
    always@(posedge clk)
        begin
            // 根据外部输入, 移动移动板位置 
        end 
endmodule 

//球模块
module ball (Xpos, Ypos); 
    output[7:0] Xpos, Ypos; 
    always@(posedge clk) 
        begin 
            // 根据外部输入, 移动球的位置 
        end  
endmodule 

//得分模块
module score (Score); 
    output[3:0] Score; 
    always@(posedge clk) 
        begin 
            // 根据外部输入, 计算得分 
        end  
endmodule 

 //主体逻辑电路 
module game (Xpos, Ypos, Hpos, Score);  

    input [7:0] Xpos, Ypos, Hpos;   //输入信号定义 

    output [3:0] Score;   //输出信号定义

    wire [7:0] Xpos_tmp, Ypos_tmp; //中间信号定义

    //引用子模块    

    move move1(Hpos);  

    ball ball1(Xpos_tmp,Ypos_tmp);  

    score score1(Score);  

    //主体逻辑

    always@(posedge clk)  

        begin  

            if(Cnt==100) //100个周期后重新开始

                begin  

                    Cnt<=0;  

                    Xpos<=50'h000000; //重新初始化球位置

                    Ypos<=50'h000000;  

                end  

            else //正常情况  

                begin  

                    Xpos<=Xpos_tmp; //将子模块的中间信号作为主体逻辑的输出信号      

                    Ypos<=Ypos_tmp;  

                end  

            Cnt<=Cnt+1'b1;     //将计时器加1  

        end  
endmodule
