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"

How do I make the projectile balls behave like actual balls?

Hi,

I'm having a hard time modifying the FPS blueprint template. My goal was to make the balls bounce instead of disappearing after hitting an object. I deleted a segment out of the projectile Blueprint and it did it's job. Then I had the problem, that the balls stop rapidly after loosing enough spped, and when they do, no force is able to move them - nor the player, nor other projectiles. After following the instruction of an answer on this site, I was able fixed that. I just had to change the collision type from ,,pojectile" to ,,physical actor" and then enable simulation. Great!

Sadly, after fixing one issue, another three popped up. Firstly: when the balls stop bouncing around, they seem to roll forever! And secondly: on random occasions the balls just float right through solid objects! There's no sense to it! I'm just standing in one place, facing one direction, and shooting at a wall in one second intervals and it's just a matter of luck if the ball bounces of the wall or clips through it like a ghost! The last issue that I'm having is that the values that I put in the Blueprint graph (the "impulse" float) do nothing unless I go back to the ,,projectile" collision type, which restores the issues I described before.

Please help me out with this! I'm sure it's not hard to get it working, but I simply can't figure it out. I've been trying for two days and I'm getting a little upset! I would really aprecciate your help!!!

Hi Bproof,

I'm sorry you're having this issue. This is a known bug after the release of 4.1.0 and it has been brought to the attention of the developers.

It did work in version 4.0.2 so as a workaround until the fix comes out, you could open the Launcher > Click the down arrow beside of 4.1.0 > Change it to 4.0.2 > Make a New FPS Project in that.

You may have to implement a few changes that Ben showed you in your previous question, but the basic functionality should be there. https://answers.unrealengine.com/questions/41352/making-objects-move-after-theyve-stopped.html

Hope that helps.

Thanks, TJ
