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"

Simple Collision Box issue in Blueprints

Can anyone Help? I added a simple "Collision Box" to the Sedan blueprint, so I could detect if a player is standing near a door. But the collision box is causing the car to lean to one side like there is some kind of force, mass, or collision pulling/pushing the car mesh (root component) down to one side.

It is something to do with collision because it only happens when collision is enabled on the "Collision Box". Here are my settings for the "Collision Box":

  • Generate Overlap Events = True

  • Collision Enabled = "No Physics Collision"

  • Object Type = "World Dynamic"

  • Collision Responses = Everything to Overlap

This behavior does not happen in v4.7.6, but it does happen in v4.8.1. What has changed?

In v4.8.1 if I take the Mesh Component (root component) and attach a "scene component" to it, then attach the "collision box" to the "scene component" the effect of force, mass, or collision pulling/pushing the car mesh (root component) does not happen any more. Have I fixed the issue or just covered it up? alt textalt text

Could some please help me understand what is happening, the more detail the better please?
