util.TraceLine
Description
Performs a trace with the given trace data.
Clientside entities will not be hit by traces.
When server side trace starts inside a solid, it will hit the most inner solid the beam start position is located in. Traces are triggered by change of boundary.
Arguments
Returns
1 table
Trace result. See Structures/TraceResult.
Can return nil if game.GetWorld or its physics object is invalid. This will be the case for any traces done before GM:InitPostEntity is called.
Example
Using a function callback as filter.
local tr = util.TraceLine( {
start = LocalPlayer():EyePos(),
endpos = LocalPlayer():EyePos() + EyeAngles():Forward() * 10000,
filter = function( ent ) return ( ent:GetClass() == "prop_physics" ) end
} )
print( tr.HitPos, tr.Entity )
Output: The trace will only hit prop_physics or world.
