Signature
native trace_line(iIgnoreEnt, const Float:fStart[3], const Float:fEnd[3], Float:vReturn[3]);
Description
Fires a trace line between two origins, retrieving the end point and entity
hit.
Notes
-
This native writes to the global engine module trace handle. Additional
trace results can be retrieved using traceresult().
-
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.
Parameters
-
iIgnoreEnt
—
Entity index that trace will ignore, -1 if trace should
not ignore any entities
- fStart — Trace starting point
- fEnd — Trace target point
- vReturn — Vector to copy trace end point to
Returns
Entity index if trace hit an entity, 0 otherwise
