如何在 C# 中插入“if”语句？ [等候接听]

Question

I am trying to make a racing game in C#. I have enemy cars coming at you and when they go past you and another one spawns in it is instant. I want it to have a 1 second delay.

I have tried using Thread.Sleep(1000); and System.Threading.Thread.Sleep(1000); (Even though I think those are the same things).

My current code is:

if (EnemyCar1.Top >= 500)
    {
       e_X = enemyPos.Next(5, 200);
       e_Y = enemyPos.Next(5, 395);
       EnemyCar1.Location = new Point(e_X, e_Y);
       System.Threading.Thread.Sleep(1000);
    }

When I try to thread it pauses the whole game and I nonthing can move.

I expected it to thread just the one method but it actually paused everything in the game, which is not what I wanted.

Answer 1

I think currently this will not work. Because you execute the Sleep Function on the UI Thread.

If you create a thread for every Car so you can let the cars "sleep".

btw: Think about using Tasks

Answer 2

You can use System.Diagnostics.Stopwatch and bind the spawn as an event which occurs when it reaches 1 second. Stopwatch is automaticaly threaded.
