所以基本上我目前正在做一个小项目，玩家将能够通过移动来对抗东西，但重力给我带来了一些问题。所以基本上，我得到了这个方法， checkGravity() 它将检查 isGravityApplicable() 是否返回 true （实体的底部对撞机（一个 Line2D）是否与一个立足点发生碰撞？（另一个 line2D））

如果 isGravityApplicable() 返回 true，则应该应用重力，但我遇到的问题是 1 像素 Y 以上的任何东西都太快了，甚至，将角色移动一个像素非常快。我不确定我是否应该修复我的游戏循环或什么？

public boolean isGravityApplicable() {
    for (Line2D line : frame.getMap().getFootholds()) {
        /*Does the bottom collider intersect the foothold?*/
        /*v THIS CHECK DOESN'T WORK CORRECTLY FOR SOME REASONS v*/
        if (!GraphicHelper.getLineCameraRelative(getBottomCollider(), frame.getCam()).intersectsLine(line)) {
            return true;
        }
        /*Above check returned false, if the velocity.y is above 1, then it might
         skip the line since it would be skipping 5 pixels for example at once.
         this check should resolve that.*/
        if (velocity.y > 0) {
            Line2D collider = getPositionToVelocityCollider();
            if (!collider.intersectsLine(line)) {
                position.y = (int) line.getY1(); //Y1 or Y2, same sh*t.
                return true;
            }
        }
    }
    return false;
}

public void checkGravity() {
    if (isGravityApplicable()) {
        if (isJumping) { //Player has jumped
            velocity.y += 1;
            velocity.y = velocity.y > TERMINAL_ACCELERATION ? (int) TERMINAL_ACCELERATION : velocity.y;
            if (velocity.y < 0) {
                isFalling = true;
            }
        } else if (isFalling) { //Player is currently falling but not from jumping. Most likely just spawned
            velocity.y = 1;
            /*Anything higher than 1 is WAY too quickly...*/
            //velocity.y += 1;
            //velocity.y = velocity.y > TERMINAL_VELOCITY ? (int) TERMINAL_VELOCITY : velocity.y;
        } else if (isJumping && isFalling) { //Player has jumped and has reached its highest point, falling back down
            velocity.y = 1;
            /*Anything higher than 1 is WAY too quickly...*/
            //velocity.y += 1;
            //velocity.y = velocity.y > TERMINAL_VELOCITY ? (int) TERMINAL_VELOCITY : velocity.y;
        } else { //Player hasn't jumped and has not started falling, he most likely just spawned
            isFalling = true;
            velocity.y = 1;
        }
    } else {
        isFalling = false;
        isJumping = false;
    }
}

提前致谢。哦，如果有什么我可以做得更好的，比如由实体周围的简单线条组成的碰撞，请告诉我。：） 谢谢。

没关系的家伙，由于某些原因，update/tick 方法在循环中被调用了两次。我猜我脑子放屁什么的。
