Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Projectile movement, collision boxes, and lost transform/scale

I have built a generic bullet using a default sphere surrounded by a collision box. It is fired using ProjectileMovement.

However it does not collide correctly UNLESS the collision box is dragged over the default scene root. Then, it collides fine with the environment, simulates physics, etc.


once the collision box is dragged up to become the default scene root, it loses all its scale and transforms and reverts to its original size, which then cannot be edited. It also drags the bullet with it, which then expands to fill the entire collision box. You can try to plug new scale/transform into the collision box manually, and while the numbers are changeable, they do not actually change anything.

I posted a video of this at https://youtu.be/7bwU4GK3rhY

Seems like you can alter the shape extents instead of the scale, and achieve the desired effect. The loss of the transforms when it is moved within the hierarchy, though, is a problem that you guys might want to look into fixing.
