Still new to UE blueprint tricks but learning so I appreciate your feedback:
To create a shotgun spread, I decided to go simple. So I created a disk projectile with collision settings.
It is working as intended but now to simulate the spread (disk) getting wider through distance while impact becoming smaller, I could not figure out how to do that in this shoot event blueprint below
I think I need to increase scale to a max size (Variable) and reduce the impact (variable) but could not find the right nodes
Also, I am not getting the disk to hit 2 close targets at once. When it hit one, it does not affect the other nearby. I tried a few combination of collisions but did not succeed
However, I recommend multiple line tracing. You can cast multiple random lines in random directions with a maximum deviation angle from your gun forward vector, imitating a cone. If you are having trouble with random line directions, you can pick your direction as simply as done in this:
Which is a cone that is seen as a circle from the perspective of your gun with the lines as the deviation of your line directions from the forward vector. You can also change the number of lines as your project requirements desire.
Now you don’t have to reduce the impulse as the hit distance increases since each line trace could add its constant impulse and the closer the object is, the more lines hit it and the more impulse it catches. Also, now you can hit multiple objects with one shot. If you are trying to be very realistic, yes, you can also take the hit distance of each line into the calculation of the impulse it is adding.
If had any issues with making the blueprint, just post here and I’ll be happy to help!
