问题描述
我正在制作一个游戏,当按下鼠标时,角色会朝着鼠标的方向加速。沿着 +x +y 到 -x -y 轴它工作,但是沿着 +x -y 到 -x +y 轴它的行为不规律,然后由于浮点异常而崩溃,就像这个 gif: 显示.我正在使用 raylib,这是我的代码:
Vector2 goToPosition = GetMousePosition();
if (IsMouseButtonDown(MOUSE_LEFT_BUTTON)) {
Vector2 relative = {goToPosition.x - ballPosition.x,goToPosition.y - ballPosition.y};
if (abs(relative.x) > abs(relative.y)) {
veLocity.x += relative.x > 0 ? 5 : -5;
veLocity.y += relative.y > 0 ? 5 * (abs(relative.x) / abs(relative.y)) : 5 * -(abs(relative.x) / abs(relative.y));
}
else if (abs(relative.x) < abs(relative.y)) {
veLocity.x += relative.x > 0 ? 5 * (abs(relative.y) / abs(relative.x)) : 5 * -(abs(relative.y) / abs(relative.x));
veLocity.y += relative.y > 0 ? 5 : -5;
}
else if (abs(relative.x) > 0) {
veLocity.x += relative.x > 0 ? 5 : -5;
veLocity.y += relative.y > 0 ? 5 : -5;
}
printf("%f,%f \n",veLocity.x,veLocity.y);
}
veLocity.x = Lerp(veLocity.x,0.1);
veLocity.y = Lerp(veLocity.y,0.1);
veLocity.x = Clamp(veLocity.x,-50,50);
veLocity.y = Clamp(veLocity.y,50);
ballPosition.x += veLocity.x;
ballPosition.y += veLocity.y;
