当我用5分击中积木时，我的积分（poang）得到高分。他们不会更新相同，有时点（poang）将是18，而highscore将是20。
（抱歉我的英语不好）

这些部分出现问题：
for (int j = 1; j < block.Count; j++) //loopar igenom alla block
{
if (boll_rect.Intersects(block[j])) //om bollen träffar rutorna
{
boll_speed.Y *= -1;
poang += 1;
block.RemoveAt(j); //tar bort gröna blocket man träffar
if (poang > 9)
{
linje_rect.Width = 60;
}
if (poang > highscore)
{
highscore++;
}
}
}
for (int k = 1; k < block2.Count; k++)
{
if (boll_rect.Intersects(block2[k]))
{
boll_speed.Y *= -1;
poang += 5;
block2.RemoveAt(k);
if (poang > highscore)
{
highscore += 5;
}
block2.RemoveAt(k);
}
}
答案 0 :(得分：1)
将highscore++;替换为highscore = poang;
和highscore += 5;与highscore = poang;
以避免高分和当前分数之间的不匹配。
