我正在进行一次跳跃运行游戏，但我的碰撞检测无法正常工作。 这是我的碰撞检测的支柱：
for(int i = 0; i < Frame.teilesArray.size();i++){
if(Frame.teilesArray.get(i).getimgInt()== 0 || Frame.teilesArray.get(i).getimgInt()== 1){
if(bounding.intersects(Frame.teilesArray.get(i).getBounding())){
Rectangle intersection = (Rectangle) bounding.createIntersection(Frame.teilesArray.get(i).getBounding());
}
}
}
这就是我试图解决的问题，但它不起作用：
public void update() {
for(int i = 0; i < Frame.teilesArray.size();i++){ //teilesArray is a Array with all tiles from the map (every block has 64x64 px)
if(Frame.teilesArray.get(i).getimgInt()== 0 || Frame.teilesArray.get(i).getimgInt()== 1){ // means that only the two special blocks will check of collision not all blocks only this blocks
if(bounding.intersects(Frame.teilesArray.get(i).getBounding())){ // bounding is the rectangle of the Player and Frame.teilesArray.get(i).getBounding() is the rectangle of one block in the Array list
Rectangle intersection = (Rectangle) bounding.createIntersection(Frame.teilesArray.get(i).getBounding()); // made a new rectangle out off the intersection
if (bounding.OUT_TOP < Frame.teilesArray.get(i).getBounding().OUT_BOTTOM ) {
ply_y += intersection.getHeight();
}
if (bounding.OUT_LEFT < Frame.teilesArray.get(i).getBounding().OUT_RIGHT && richtung == 2) { //richtung links
ply_x += intersection.getWidth();
}
if (bounding.OUT_BOTTOM > Frame.teilesArray.get(i).getBounding().OUT_TOP ) {
ply_y -= intersection.getHeight();
}
if (bounding.OUT_RIGHT > Frame.teilesArray.get(i).getBounding().OUT_LEFT && richtung == 1) { //richtung rechts
ply_x -= intersection.getWidth();
}
}
}
}

答案 0 :(得分：0)
如果是这样的话，请尝试使用此代码：
// adding variables for the object the player can collide with
double minX = Frame.teilesArray.get(i).getBounding().getMinX();
double maxX = Frame.teilesArray.get(i).getBounding().getMaxX();
double minY = Frame.teilesArray.get(i).getBounding().getMinY();
double maxY = Frame.teilesArray.get(i).getBounding().getMaxY();
if (bounding.getMinY() < maxY && bounding.getMaxY() > minY ) {
// collision is vertical
if (bounding.getMaxY() > minY) {
// bottom of player has passed the top border of collision object, move up
ply_y -= intersection.getHeight();
} else {
// opposite case, move down
ply_y += intersection.getHeight();
}
}
if (bounding.getMinX() < maxX && bounding.getMaxX() > minX ) {
// collision is horizontal
if (bounding.getMaxX() > minX) {
// right border of player has passed the left border of collision object, move left
ply_x -= intersection.getWidth();
} else {
// opposite case, move right
ply_x += intersection.getWidth();
}
}
