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"

3d Projectile Motion with drag(air resistence)

Hey so due to the limitations of unreal's projectile component at high speeds i decided to write my own and everything works fine i'm doing this using the normal projectile equations and getting the speed in each axis by splitting it using the angles know when shooting. Now the problem came when i went to add drag to the equations i don't know if i was given the equations wrong or if i'm just writing the wrong so what i'm asking is if my equations are wrong and what i need to fix or if you can point me to a place where the equations are?

Here are my blueprints: alt text

This where i add the drag to find the new accelerations using the equation -kv/m - g and -kv/m for x and y

This is where i calculate the next distance

Then here is where i set the new velocities: alt text
