Hello,

Can someone help me to not allow plant lasermine over other players!.

public bool: CanPlant( iPlayer ) {
    static Float: flOrigin[ 3 ];
    entity_get_vector( iPlayer, EV_VEC_origin, flOrigin );
    
    static Float: flTraceDirection[ 3 ], Float: flTraceEnd[ 3 ], Float: flTraceResult[ 3 ], Float: flNormal[ 3 ];
    velocity_by_aim( iPlayer, 64, flTraceDirection );
    flTraceEnd[ 0 ] = flTraceDirection[ 0 ] + flOrigin[ 0 ];
    flTraceEnd[ 1 ] = flTraceDirection[ 1 ] + flOrigin[ 1 ];
    flTraceEnd[ 2 ] = flTraceDirection[ 2 ] + flOrigin[ 2 ];
    
    static Float: flFraction, iTr;
    iTr = 0;
    engfunc( EngFunc_TraceLine, flOrigin, flTraceEnd, 0, iPlayer, iTr );
    get_tr2( iTr, TR_vecEndPos, flTraceResult );
    get_tr2( iTr, TR_vecPlaneNormal, flNormal );
    get_tr2( iTr, TR_flFraction, flFraction );
    
    if( flFraction >= 1.0 ) {
        zp_colored_print( iPlayer, 1, " You must plant the Tripmine on a Wall" );
        
        return false;
    }
    
    return true;
}

Found it.

Thanks anyway.

_IsPlayer(get_tr2( iTr, TR_pHit)) && get_tr2( iTr, TR_pHit) != 0

use the trace outputs
