支持物体掉落和toolbar的联动

物体掉落 添加了游戏引擎。 但是如何设置碰撞体的 group。保证物体只和地面碰撞 不和 其他物体碰撞呢？

i want to A an A not collide each others . but A and B can collide. How to set CollisionGroups and SolverGroups ? Sorry its hard to understand the document.So I just ask……
[16:36]aceeri: So you'd have an A membership which I'll say is 0b01 and a B membership which I'll say is 0b10
[16:37]aceeri: for the A group you don't want it to collide with A but you do want it to collide with B, so you'll take the B membership, but not the A one for the filter
[16:37]aceeri: which would be 0b10
[16:37]aceeri: and for the B group I'm assuming you want them to collide with themselves so it would be both the B and A members, which would be 0b11
[16:38]aceeri: you can think of it as more like:
membership is the group, filter is which groups you want to collide with
[22:57]robot Zhou: okay thanks . I just not understand what is 0b01 or 0b11 means? 0b01 = [1] and 0b11 = [2] ?
[22:58]robot Zhou: Oh, I may get it. I will try thanks.
