Methods for creating the best bullets?

What is the most performance efficient way to make a bullet in a gun? With the context of performance being server stability and "No Lag", what's the best way to set up a gun to fire bullets in a Filtering Enabled environment? Something that can handle bullet drop off, bullet time, penetration, and perhaps particle effects on impact?

Would a normal part with collision turned off and velocity spiked way up in one direction handle this?

Is Raycasting the best way to go about it?

Are there other ways to do it?

Hi Car187,

I recommend making a physical bullet and firing the bullet from the barrel of the gun to the position that the barrel is facing using the .lookVector of the barrel.

#Use the following:

BodyVelocity

You make this inside of every bullet. The MaxForce should be set to math.huge() in all coordinates because bullets are supposed to be fast.

.lookVector

You use this for setting BodyVelocity's Velocity. With this you can make the part go in the direction a part is facing, which is what a bullet does when you fire it from a gun. It goes in the directi**on the barrel is facing.

##A straight part on the barrel.

I recommend this because when you make a gun and model it and all, it becomes hard to tell which direction is straight with it, so I would just say you can either make an invisible non-colliding part right on the barrel, or just add a part to every barrel that faces straight in the direction the barrel is facing. You can find which direction it's facing by using a decal. One of decal's property is 'Face' and you can use this to detect which way is the front and I think the .lookVector uses the front side.

#Why use this and not just raycasting?

Raycasting doesn't take into account proper physics that should affect a gunshot, like aerodynamics and such. Also, raycasting doesn't take into account the amount of time that it would take for the bullet to reach from the barrel to the target, and a target could possibly avoid dying if he/she is fast enough. The short reason is that raycasting doesn't have a speed you can set, but, BodyVelocity does. However, I can understand using raycasting because you are seeking ultimate efficiency over realistic goals. So, for efficiency over realistic system, I would say ray casting is pretty good then but, you will have many complaints possibly about it because it would limit gameplay but, increase smoothness. So, you have to choose of the better. You can reduce the lag with physical objects by using StreamingEnabled, so you can also have a balance but, StreamingEnabled has it's own limitations which you can find here.

##Ultimately, I hope I helped.

Thanks,

The best way to create realistic "bullets", to not actually use parts, but to use RayCasting.
