How to create a railgun with MBF21?

[OkDoomer174]

I've been stuck on this for quite a while now. What I'm looking for is either:

1. A way to create a super fast-moving projectile that won't skip collision checks
2. A way to fire a single BFG tracer-type thing
3. A way to fire a hitscan shot and create a thing on the target

Any help would be much appreciated.

MBF21 defines new code pointer types, but it doesn't define a new physics spec. Anything moving faster than its radius is guaranteed to miss objects and walls within its movement, and there's nothing you can do about that.

Look here

1. A_WeaponProjectile(type, angle, pitch, hoffset, voffset). Create new type separate and add speed high number

2. Do you want that BFG shot one ball?

3. I didn't quite get that.

No, essentially what I want is a projectile that fires a BFG spray, but only one tracer instead of a whole bunch.

Essentially, it should fire a hitscan shot and spawn an actor on top of the thing it hits, similarly to a blood splat.

Say, this got me thinking, I could probably make the radius bigger to make skipping collisions not a problem. Then again, projectiles seem to have problems with autoaim at especially high speeds...

Thinking out loud: Why not just make the railgan.bex shot from zdoom standard in mbf21?

I once experimented with having a hitscan attack that makes multiple shots with no deviation, which mostly works. I even added an invisible projectile that flies by and spawns particles in spiral pattern.

It worked, but I didn't like it.

I'm mapping for Discord hosted community project that has a "hunting rifle" which is a shotgun that fires 5 hitscans in a single line, passing through enemies killed by the initial shots functioning similar to a railgun (vs monsters).

 

If you want to take a look at the *wip resrouce pack it's available in my projects folder (denapsed2v2.wad) if you're not a member of @Napsalm's Discord.
He does some amazing stuff with dehacked and would be a good person to ask directly as he's usually open to helping out with dehacked.

As a brain-storm. The archvile attack spawning the flame may be a way to add an additional sprite/dehacked to spawn something on a target.

 

*Please note - I am newer to DW and not familiar with a lot of other dehackers in the community and have not actually made dehacked stuff at this point.

In the Vesper weapon mod, I saw something similar in its spring effect to the Railgun. But it doesn't shoot through all enemies.
