hello, I have create a barrel and I wants to explode it.

here my ordering of choot:

my probléme is that barrel_body did not detecté !

help me please


ps:sorry for my English

It's the wrong board...

Hi stpc

Ok first, as noticed by Vincentv, you're not on the good board (dbpro should be the good one).

And no french accents in english... ^^ That's not making thing understandable.

Do you have the same problem that we've discussed on the french forum?

You may also make notice that you're using Newton Wrapper for your program. That could help because nobody can understand what is your problem!

ok, I use the order of choot of the demo 5 of newton and I would like to explode the one barrel, but the HitBody function = NDB_RayCastGetBody() does not want to return me the number of the body touched to inflict an action to him!
for my test
boum = NDB_RayCastGetBody(barrel)
if boum then end
barrel is a object creates as limp them of the demo!

here my ordering of choot:

if mouseclick()=1 and MOUSE =0 and muni>0
MOUSE =1
tir=1
DEC muni,1
dec hud_bullet,1



`user wants to shoot! let's cast a ray with Newton and see if we've hit something!
x1# = camera position x() : y1# = camera position y() : z1# = camera position z()

`get a unit vector in the direction the player is facing, by moving the camera 1 unit!
move camera 1.5
x2# = camera position x() : y2# = camera position y() : z2# = camera position z()
move camera -1.5

`we will cast a ray 500 units long.
dx# = x2# - x1#
dy# = y2# - y1#
dz# = z2# - z1#

x2# = x1# + (dx# * 500.0)
y2# = y1# + (dy# * 500.0)

my probléme is that barrel_body did not detecté !

help me please

do you have solution please

he just told you a solution
