java 2d平台冲突错误
当角色走进一堵他们无法穿过的墙时,但是当跳进一堵墙时,玩家会被传送上下,这取决于你击中瓷砖的高度
我怎样才能让玩家在撞墙时摔倒呢
运动和碰撞检测发生在播放器中。爪哇
我认为这与签入有关,如果玩家站在一个区块上(for循环中的第一个签入),但我不确定

以下是检查碰撞的方法:
public void collisionCheck(){
for (ArrayList<Integer> tile: Game.tileCoordinates){
//current row of the player
int row = y / Game.TILE_SIZE;
// the row below the player
int rowBelow = y / Game.TILE_SIZE + 1;
// the column the left of the player is in
int columnLeft = x / Game.TILE_SIZE;
// the column the right of the player is in
int columnRight = (x + width) / Game.TILE_SIZE;
// check if the player goes through the block below
if (tile.get(1) / Game.TILE_SIZE == rowBelow){
if ((tile.get(0) / Game.TILE_SIZE == columnLeft ||
tile.get(0) / Game.TILE_SIZE == columnRight)) {
y = tile.get(1) - height;
if (jumping) {
jumping = false;
Game.spacePressed = false;
dustAfterShowed = false;
xAfterJump = x;
yAfterJump = y;
}
if (falling){
falling = false;
}
}
}
// check if the player goes through the side of a block
if (y <= tile.get(1) && y + height <= tile.get(1) + Game.TILE_SIZE &&
y + height >= tile.get(1) && row == tile.get(1) / Game.TILE_SIZE) {
// left side
if (x + width >= tile.get(0) && x <= tile.get(0)) {
x = tile.get(0) - width;
}
// right side
if (x + width >= tile.get(0) + Game.TILE_SIZE &&
x <= tile.get(0) + Game.TILE_SIZE) {
x = tile.get(0) + Game.TILE_SIZE;
}
}
// check if the player hits a block from below
if (tile.get(1) / Game.TILE_SIZE == row &&
(tile.get(0) / Game.TILE_SIZE == columnLeft ||
tile.get(0) / Game.TILE_SIZE == columnRight)){
if (jumping) {
y = tile.get(1) + Game.TILE_SIZE;
velocity = 0;
}
}
}

我通过添加一些布尔值来修复它,当玩家从侧面撞到墙上时,它现在不再检查底部瓷砖的碰撞(使玩家摔倒,而不是停留在空中)
检查顶部瓷砖碰撞时,请提前检查。如果不提前检查,它会检测到侧面碰撞,因为左上角和右上角的像素都在平铺中
