Updated Space Engineers script for listing Speed|Time|Position.

SpeedTimeCoord.cs

void Main()

    // Get blocks 
    var blocks = new List<IMyTerminalBlock>(); 

    // Get the antenna 
    GridTerminalSystem.GetBlocksOfType<IMyRadioAntenna>(blocks); 

    if(blocks.Count > 0)

        String CurrentName = Block.CustomName; 

        // Get the fragments (or get one fragment) 
        String[] Fragments = CurrentName.Split('|'); 

        // Get coordinates (VRageMath.Vector3D, so pull it in the ugly way) 
        double x = Math.Round(Block.GetPosition().GetDim(0), 4); 
        double y = Math.Round(Block.GetPosition().GetDim(1), 4);

        double X = 0;

            OldTime = Convert.ToInt64(Fragments[1]); 

            // Vomit a bit here because this is how we have to store variables at the moment ... 
            string[] Coords = Fragments[2].Split(','); 
            X = Math.Round(Convert.ToDouble(Coords[0]), 4); 
            Y = Math.Round(Convert.ToDouble(Coords[1]), 4);

            // Nothing fancy here 
            Distance = System.Math.Sqrt( 
                ((x-X)*(x-X)) + ((y-Y)*(y-Y)) + ((z-Z)*(z-Z)) 
            ); 
        } 

        // If the base coordinates 
        if (Distance != 0 && X != 0 && Y != 0 && Z != 0 && OldTime != 0) 
        { 
            // Update time 
            var Time0 = System.DateTime.FromBinary(OldTime); 

            // We have 's' for m/s. 
            var TimeDelta  = (Time1 - Time0).TotalSeconds; 

            // We have our distance 
            Speed = Distance / TimeDelta; 
        } 

        // Speed|Time|X,Y,Z 
        String NewName = Speed.ToString() + "|" + 
            CurrentTime.ToString() + "|" + 
            x.ToString() + "," + y.ToString() + "," + z.ToString();

        // Store it 
        Block.SetCustomName(NewName); 

        // Show it on the HUD so we can check it 
        Block.RequestShowOnHUD(true); 
    } 
}

Is there a way to get the orientación of a block un degrees ?

Ver y helpfull example btw :)
