Bullettrace - Yamato - 07-18-2011

Hello, Nyan Cat

I am going to explain something about this usefull command.

A bullettrace is something like the line that a bullet forms. It has a start and a end. Basically its structure is like this:

Code:
RandomTrace = Bullettrace(start,end,true,self);

The start is obvious what it is: the position from the one it starts.
The end is the position where it ends, Tongue

.
The True is a command that will detect players or not, if you want it to detect players put true, if not false.
The self I putted is a entity that wont be affected by the trace, with self, it wont detect the own player or whatever you are using self for.

A example of usage:

Code:
ForwardTrace = Bullettrace(self getEye(),self getEye()+anglestoforward(self getplayerangles())*100000,true,self);

This will find the point that is forward to you at a scale of 100000. If you want to get the position, call it like this:

Code:
ForwardTrace["position"]

You can get the entity that is in that point with:

Code:
ForwardTrace["entity"]

In a bullettrace there is also a fraction, that can have a value beetween 0 and 1, 1 means that the trace has completely crashed against the surface(I am not very sure about this, is just what I tested, correct me if I am wrong)

You can call it like this:

Code:
ForwardTrace["fraction"]

There is also the surfacetype, that is the type of surface that is in the point of the bullettrace, like water,sand or mud:

You can call it like:

Code:
ForwardTrace["surfacetype"]

This is a list of them, I think that is complete, I putted it in alphabetical order:

Code:
asphalt
bark
brick
carpet
cloth
concrete
default
dirt
flesh
foliage
glass
grass
gravel
ice
metal
mud
paper
rock
sand
snow
water
wood

I think that this is all, I hope I helped a bit, if I said something wrong correct me.

Yamato, Awesome

Fuu

you just ruined something epic I wanted to release with something epic that not everyone knew

RE: Bullettrace - AZUMIKKEL - 07-18-2011

Didn't know about the ["stuff"]. Thanks you! I think this counts for Black Ops too, yes? Should move/copy it there c:

RE: Bullettrace - Pozzuh - 07-18-2011

Yep, works for black ops.

RE: Bullettrace - Nukem - 07-18-2011

Overall this is a nice tutorial for people who don;t know about this. (I do Nyan Cat

)

P.S.
trace["position"] is where the trace ends at an object/material you can't shoot through, not always at

Code:
self getEye()+anglestoforward(self getplayerangles())*100000

RE: Bullettrace - iAegle - 08-24-2011

can I make it so it ignores every player not just self?

like

Code:
bulletTrace( eyePos, blabla_end, true, level.players );

I think he wants to ignore people he wants so the bullettrace won't crash and complete, make another variable like this:

Code:
Ignoretracem = ignoretracem(); 
bulletTrace( eyePos, blabla_end, FALSE, Ignoretracem);

Then put something like this:

Code:
ignoretracem() 
{ 
 if(blablabla) 
 return variable; 
}
