canPlaceSentry()

Hello, I'm reworking my sentry gun to cod mw2 + style. How can I check whether the turret is in the wall or located in the wrong place (red/yellow model thing)? Should I use 3 bullettrace to check collision with x y z axis? Have you any better ideas?

Regards, Robson.

either that or play around with physicstrace() & positionwouldtelefrag()

Can you explain a bit how does "physicstrace" work and how can I use it?

hi here this is an example

deploy()
{
self endon("disconnect");
self endon("death");

angles = self getPlayerAngles();
start = self.origin + (0,0,40) + maps\mp\_utility::vectorScale(anglesToForward( angles ), 20);
end = self.origin + (0,0,40) + maps\mp\_utility::vectorScale(anglesToForward( angles ), 38);

left = maps\mp\_utility::vectorScale(anglesToRight( angles ), -10);
right = maps\mp\_utility::vectorScale(anglesToRight( angles ), 10);
back = maps\mp\_utility::vectorScale(anglesToForward( angles ), -6);

canPlantThere1 = BulletTracePassed( start, end, true, self);
canPlantThere2 = BulletTracePassed( start + left, end + left + back, true, self);
canPlantThere3 = BulletTracePassed( start + right , end + right + back, true, self);
if( !canPlantThere1 || !canPlantThere2 || !canPlantThere3 )
{
return false;
}


trace = bulletTrace( end + (0,0,100), end - (0,0,300), false, self );
if(trace["surfacetype"] == "default" || trace["surfacetype"] == "none")
{

return false;
}


return true;
}

physicsTrace() is a volume trace that checks against the players volume

physicstrace ignores players on a server. It is better for returning a vector than bullettrace is.

No, physicstrace ignores players.

That's bullettrace Pal. Not physicstrace:

Code:

---

PhysicsTrace( <start>, <end> )
Module: Trace

Summary:

Physics trace, ignoring characters. Returns the endpos vector.


Example:

endpos = PhysicsTrace( start, end );



Required Args:

    1 : <start> The start point
    2 : <end> The end point

physicsTrace is just a volume-trace, easier said, it tells you the last possible place between startVec and endVec where a player could stay

The script function specifically states: "ignoring characters". Ignoring characters = ignoring players.

I dont have any doubts about that =)

Just said that it will return the place where a player could possibly stand -> volumetric trace of the players collision cylinder
