It's ideal if the object is 1 unit,

It's ideal if the object is 1 unit, correct. If it's that big you won't get errors about collision shapes being too small. If your entire scene is only 2 units high then it seems the objects would have to be much smaller than 1 unit. The only way to fix the problem is to scale the objects up, because the vertices are physically too close and there's nothing the engine can do about that.

結果 (繁體中文) 1:

如果物件是 1 個單位，正確，它是理想的。如果它是，大你不會得到關於碰撞形狀太小的錯誤。如果你整個的場景只是 2 個單位高然後似乎物件必須要遠小於 1 個單位。解決問題的唯一方法是要縮放的物件，因為頂點身體靠得太近，還有什麼能發動機能做些什麼。

結果 (繁體中文) 2:

這是理想的，如果對象是一個單位的，正確的。如果這是大的，你不會得到有關碰撞的形狀太小的錯誤。如果整個場景是只有2個單位高則似乎對象必須是比1個單位小得多。解決這個問題的唯一方法是高達縮放對象，因為頂點是身體過於接近並沒有什麼發動機可以做到這一點。
