[Steam]Poly Bridge最少花费过关攻略（撰写，23日更新）

Early Access Build 0.71b。具体数据和判定会因版本的变更，而有所不同。

 

BUG

1. 编辑模式下，删除一个已建的元件（木头或别的），然后撤销这次删除操作，这时Budget Used不会改变。
   

 

说明&经验

1. 相同架构下，Budget Used会有个位数内的差异；
2. 理论上等边三角形的支撑力最大，而直角等腰三角形具有支撑力大和便宜的特点；
3. 如果需要2层直角等腰三角形来铺设，则可以用等边三角形代替；
4. 支撑力已足够时，可降低三角形的高度，以节省用料费用；
5. Stress为On，能观察到支撑点的负重情况；
6. 在同一个桥梁结构的情况下，每次变更之后Max Joint Stress的值可能会改变。当该值达到或超过100%时，桥梁的节点过最大付总而崩塌。因此在结束时，该值越接近100%，则表示该桥梁结构越不稳定（并不保证每次都能通过）；
7. 标红数值的关卡，需要多尝试才有可能按如图所示通过；
