Very cool, good job. I didn't know you could create beams as entities.

Can you explain what a BEAM_HOSE is?

Are you able to use this method to create other types of beam messages? (ie. TE_BEAMSPRITE, TE_BEAMTORUS, TE_BEAMDISK, TE_BEAMCYLINDER, TE_BEAMFOLLOW, and TE_BEAMRING)

I assume using this is equivalent to doing MSG_BROADCAST, is there a way to show only to a single player?

One thing I think you should change is letting iSpriteIndex be optional in Beam_Create and Beam_Init; you should be able to find the index for the sprite if you have the name (or vice versa).

You should also try to put a little more documentation for each macro/function to make it easier to understand for beginners.

Overall good job though; I'm sure I will end up using this some day.

Never heard of env_laser/env_beam/beam entities ?

Quote:

BEAM_HOSE is the same as BEAM_POINTS, except your provide a direction instead of an end point.

No. It's specific. Though you can try to reproduce the same effect.

Like any others entities, if you want to filter, I guess you have to use AddToFullPack.

Removed iSpriteIndex argument in Beam_Create and Beam_Init stocks.

Hello;

Using this shizzle for a new mod of me.
Pretty hard to use without examples anyway;

I think you forgot to include <xs>, bcs I had errors when I compiled.

[Edit]
- Used first time, and worked.
- This is awesome, thanks!

[Edit #2]
- Is it possible to detect touch?

Touch works here now,

but after testing, and I move sometimes..
at a time the line doesnt come anymore, it says an entity number.. but nothing shows

arround entitynumber 90

How to solve this?
