native
trace_line
Syntax
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.
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 |
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
