How can i calculate angle, velocity, smoke when the bullet hit wall?
Can i use TE_MODEL to create the sprite?

[Hyper Nova]

explain more please.

I dont understand how the smoke must be, mayby give picture or something?
if you want to change angle, velocity and such stuff then you need to create new entity.

Hook Ham_TraceAttack and get the hit point with get_tr2 TR_vecEndPos.

I know that, but i want create smoke at the point when bullet hit something not human.
Of course,TE_SPRITE cant be used in this case.

get_user_aimning(id,victim,bh) - if 0<victim<=get_max_players() then is not human
get_user_origin(id,origin,3) - aim pos

[tei1995]

Men, i want to create smoke, not get aim origin.

[GordonFreeman (RU)]

create smoke at aim origin (problem?)

[tei1995]

No,create smoke at bullet hit point. Use TraceAttack to get the endposition.
My english suck!

to calculate angle you can use my method in http://forums.alliedmods.net/showthread.php?t=183454

create enitity and start traceline to then by spining right now.

I'm not sure about this calculate...
Do you have c++ code of wallpuff?
