Hello all, I build a "worms" game. In the start of the develop,I did that the player would flate the terrain below him. As the game develops I want the player to have the ability to move. So I calculate the angle I need to rotate him relatively to the terrain. (I got an array with all the terrain heights and the player's width is 40). [source lang="csharp"]Vector2 positon2=new Vector2(players[i].Position.X+30,terrainContour[(int)players[i].Position.X+30]);Vector2 position=new Vector2(players[i].Position.X+10,terrainContour[(int)players[i].Position.X+10]);Vector2 distance = position - positon2;players[i].BaseAngle =MathHelper.PiOver2+(float)Math.Atan2(distance.X,-distance.Y);players[i].WeaponAngle = MathHelper.ToDegrees(players[i].BaseAngle+MathHelper.PiOver2);[/source] Till now all good the player is rotate relatively to the terrain and the weapon also. But now I want to place the weapon in the middle of the player. Before I rotated all the position of the weapon relateively to the player position was [source lang="csharp"] new Vector2(20,-10)[/source] But now I need to treat the BaseAngle too. I thought a matrix should do it so I did this matrix: [source lang="csharp"]Vector2 WeaponRot = Vector2.Transform(new Vector2(0, 0), Matrix.CreateRotationZ(MathHelper.ToRadians(player.BaseAngle))*Matrix.CreateTranslation(new Vector3(xpos + 20, ypos - 10, 0)));[/source]
and used the WeaponRot as the position. Unfortunately, It didnt work as some of the rotations works and some not. Thanks for reading. Could you please help me?
