trace_line

Syntax

native trace_line(iIgnoreEnt, const Float:fStart[3], const Float:fEnd[3], Float:vReturn[3]);

Usage

Entity index that trace will ignore, -1 if trace should
not ignore any entities

Trace starting point

Trace target point

Vector to copy trace end point to

Description

Fires a trace line between two origins, retrieving the end point and entity
hit.

Note

This native writes to the global engine module trace handle. Additional
trace results can be retrieved using traceresult().

Note

This native returns 0 if the trace did not hit anything. As 0 is an
entity index that is considered to be a valid value for a trace hit
("worldspawn"), this native can potentially return a misleading value.
Check other components of the trace result to verify the entity index.

Return

Entity index if trace hit an entity, 0 otherwise
