这是我在 spaceship 类中使用的代码:
class SpaceShip extends GameObject
{
//contructor for the player's spaceship
SpaceShip()
{
x = width/2;
y = height/2;
dx = 0;
dy = 0;
}
void show()
{
fill(193, 152 , 240);
//This is what is needed to be changed into an image whilst keeping this as a sort of hitbox per-say
rect(x, y, 50, 50);
}
void act()
{
dx = 0;
dy = 0;
if(upkey) dy = -5;
if(leftkey) dx = -5;
if(rightkey) dx = 5;
if(downkey) dy = 5;
//if(spacekey)//fire
x = x + dx;
y = y + dy;
}
boolean hasDied()
{
return false;
}
}
如果你们可以通过代码或发布方式帮助我(我还没有真正使用过这样的网站),那么一定要告诉我,我会尽力回复你们并更新这篇文章。
Edit1:GameObject 只是一些次要代码,这些代码都在这个类中说了,这是我的手动代码,它被用来覆盖,仅此而已 - 使用的类是:show()、act 和 hasDied,GameObject 中的每个类都是空的,但有一些异常(exception)。如果您想进一步了解,请评论,我会尽力回答。
Edit2:这是我对这个问题的最终目标是: 使矩形透明并显示图像(在本例中是一艘宇宙飞船),同时保持矩形功能用作受到伤害等的碰撞箱。 (希望这有助于消除对我想要实现的目标的任何误解)。
Edit3:谢谢伙计,这就是我现在所处的位置以及什么 当前的代码是:
PImage img;
class SpaceShip extends GameObject
{
//contructor for the player's spaceship
SpaceShip()
{
img = loadImage("SpaceShipSprite1.png");
x = width/2;
y = height/2;
dx = 0;
dy = 0;
}
void show()
{
fill(LightPurple_SpaceShip);
//This is what is needed to be changed into an image whilst keeping this as a sort of hitbox per-sa
rect(x, y, 50, 50);
image(img, x, y, 50, 50);
}
void act()
{
dx = 0;
dy = 0;
if(upkey) dy =-5;
if(leftkey) dx =-5;
if(rightkey) dx =+5;
if(downkey) dy =+5;
if(firekey) engine.add(new Bullet());
x = x + dx;
y = y + dy;
}
boolean hasDied()
{
return false;
}
}

编辑4(最终编辑):这是所有想要做类似事情的人的最终完成版本,感谢所有帮助我解决这个困境的人,并期待将来提出更多问题。
PImage img;
class SpaceShip extends GameObject
{
//contructor for the player's spaceship
SpaceShip()
{
img = loadImage("SpaceShipSprite1.png");
x = width/2;
y = height/2;
dx = 0;
dy = 0;
}
void show()
{
noStroke();
noFill();
//This is what is needed to be changed into an image whilst keeping this as a sort of hitbox per-sa
rect(x, y, 50, 50);
image(img, x - 24.8, y, 50, 50);
}
void act()
{
dx = 0;
dy = 0;
if(upkey) dy =-5;
if(leftkey) dx =-5;
if(rightkey) dx =+5;
if(downkey) dy =+5;
if(firekey) engine.add(new Bullet());
x = x + dx;
y = y + dy;
}
boolean hasDied()
{
return false;
}
}
最佳答案
使用 loadImage
和 image
函数,如 documentation 中所述。 :
PImage img;
SpaceShip() {
// Images must be in the "data" directory to load correctly
img = loadImage("spaceship.jpg");
...
}
void show() {
image(img, x, y);
}
