这是我在太空飞船类中使用的代码:
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;
}
}
如果你们可以在代码或发布方式方面帮助我(我还没有真正使用过这样的网站),那么请务必告诉我,我将尽力答复你们并更新此信息帖子。
Edit1:GameObject只是一些次要代码,在该类中都是如此,这是我的手动代码,它曾经被覆盖,仅此而已-所使用的类是:show(),act和hasDied,每个类除了某些例外,GameObject中的所有这些类都为空。如果您想进一步了解,请发表评论,我会尽力回答。
Edit2:这是我对这个问题的最终目标是: 为了使矩形透明并显示图像(在本例中为一艘太空飞船),同时还要使矩形功能用作承受伤害的命中盒,而不要造成伤害。 (希望这有助于清除对我要实现的目标的任何误解。)
Edit3:谢谢队友,这是我现在的位置以及 当前代码是:
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最终版,感谢所有帮助我解决这一难题并希望将来提出更多问题的人。
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;
}
}
答案 0 :(得分:0)
使用documentation中所述的loadImage
和image
函数:
PImage img;
SpaceShip() {
// Images must be in the "data" directory to load correctly
img = loadImage("spaceship.jpg");
...
}
void show() {
image(img, x, y);
}
