C# 精灵与产卵
我有一艘正在产卵的船。有两种类型：轨道炮子弹和导弹。导弹发射正常，但轨道炮炮弹总是在飞船前方产生大约100个像素（或者至少看起来是这样）。我不知道为什么会这样。还有，有两个炮塔，当它从一个炮塔发射时，它应该将布尔值设置为true，以使它从另一个炮塔发射；当它从该值中激发时，它会将布尔值设置回false，以此类推。它总是从第一个发射出去。同样，我也不知道为什么。我一整天都在用头撞这个。这是我的密码：C# 精灵与产卵,c#,xna,sprite,C#,Xna,Sprite,我有一艘正在产卵的船。有两种类型：轨道炮子弹和导弹。导弹发射正常，但轨道炮炮弹总是在飞船前方产生大约100个像素（或者至少看起来是这样）。我不知道为什么会这样。还有，有两个炮塔，当它从一个炮塔发射时，它应该将布尔值设置为true，以使它从另一个炮塔发射；当它从该值中激发时，它会将布尔值设置回false，以此类推。它总是从第一个发射出去。同样，我也不知道为什么。我一整天都在用头撞这个。这是我的密码： using System; using System.Collections.Generic;
