[dropcap2]Q[/dropcap2] I just updated, where did the 2D ColliderGen menu go?
[dropcap2]A[/dropcap2] It’s now under Component – 2D ColliderGen.
[dropcap2]Q[/dropcap2] Does 2D ColliderGen work with other 2D frameworks?
[dropcap2]A[/dropcap2] Yes – just attach an AlphaMeshCollider to your object.
Then by default, the main texture of the object is used. If your GameObject has no texture attached, or in case of a texture atlas, you may need to set the Advanced Settings – Custom Texture parameter to provide the desired texture. Please visit this documentation page for further info.
[dropcap2]Q[/dropcap2] Does 2D ColliderGen have any impact on the game’s framerate?
[dropcap2]A[/dropcap2] No – it does nothing but add a MeshCollider or PolygonCollider2D.
Be sure to use the outline vertex count parameter of the AlphaMeshCollider to optimize the vertex count according to your shape – the fewer vertices, the better.
[dropcap2]Q[/dropcap2] Can I use 2D ColliderGen to update colliders during runtime?
What if I can’t precompute them?
[dropcap2]A[/dropcap2] Yes – Unity4.3 Sprite Animations are supported out of the box.
If you can’t precompute them, the answer is still yes, but there is some coding involved for now.
In the second case, please visit the Runtime Collider Generation page for instructions. If you have any problems, drop us a message and we will help you with the coding details. OrbitGames have successfully used our tool to create a planet digging game called ‘Plannit’ which performs well on mobile. Visit their Youtube channel and watch the Trailer here:

[dropcap2]Q[/dropcap2] There are no front- and back-caps on the MeshCollider, but I need them – what can I do?
[dropcap2]A[/dropcap2] There are two solutions for this problem
The easy way is to switch the AlphaMeshCollider output collider type to PolygonCollider2D.
If that’s not an option, check “force convex” at the AlphaMeshCollider and tick “convex” at the MeshCollider component, then the front and back caps are added automatically. We are sorry to say that we don’t offer a solution for concave MeshCollider caps.
