hey,
if you use a medic plugin or something that make you gain health,
you probably want the plugin to check if the health exceeds pcvar(p_health).
you can do this by replacing the "make_footsteps(param[])" function with this.
public make_footsteps( param[] )
{
new id = param[0];
if ( get_user_health( id ) > get_pcvar_num( p_health ) || !is_user_alive( id ) || !is_user_connected( id ) )
{
if( task_exists( TASK_ID + id ) )
{
remove_task( TASK_ID + id );
}
g_isDying[id] = false;
return;
}
if ( !get_pcvar_num( p_active ) || get_user_speed( id ) < 120 )
{
return;
}
new origin[3];
get_user_origin( id,origin );
if( pev( id, pev_bInDuck ) == 1 )
{
origin[2] -= 18;
}
else
{
origin[2] -= 36;
}
new Float:velocity[3], ent_angles[3], ent_origin[3];
new ent = engfunc( EngFunc_CreateNamedEntity, engfunc( EngFunc_AllocString, "info_target" ) );
pev( id, pev_v_angle,ent_angles );
pev( id, pev_origin,ent_origin );
if( ent > 0 )
{
ent_angles[0] = 0; //tried changing to 180
if(g_decalSwitch[id] == 0)
{
ent_angles[1] -= 90;
}
else
{
ent_angles[1] += 90;
}
set_pev( ent, pev_origin, ent_origin );
set_pev( ent, pev_v_angle, ent_angles );
velocity_by_aim( ent, 12, velocity );
engfunc( EngFunc_RemoveEntity, ent );
}
message_begin( MSG_BROADCAST, SVC_TEMPENTITY, origin );
write_byte( 116 );
write_coord( origin[0] + floatround( velocity[0] ) );
write_coord( origin[1] + floatround( velocity[1] ) );
write_coord( origin[2] );
write_byte( decals[g_decalSwitch[id]] );
message_end();
g_decalSwitch[id] = 1 - g_decalSwitch[id];
return;
}
it also removed the "Tag mismatch" error from ent_angles[0].
But if you want this plus a neat and nice coding and a few small changes,
then you can just replace it all:
