XNA, animering
Jag håller på att göra ett spel men har fastnat lite på animationen för gubbens ben. (Gubben som jag använder nu är en test gubbe om ni undrar varför den är röd)
YouTube - Leg animation problem.avi
Det är mening att benet ska vridas från uppe sidan och inte nedre sidan av benet dessutom ska det inte gå snurra i ett varv som den gör. Har försökt att fixa det i mer än en vecka men kan inte komma på en lösning.
class Character : GameObject
{
public static Matrix[] meshLeg = new Matrix[3];
public static float[,] LegPosition = new float[3, 3];
public Character()
{
for (int i = 0; i >= 2; i += 1)
{
meshLeg[i] = new Matrix();
for (int j = 0; j >= 2; j += 1) {
LegPosition[i, j] = 0;
}
meshLeg[i] = Matrix.CreateTranslation(new Vector3(0, -0.25f, -3.4f)) * Matrix.CreateRotationX(LegPosition[i, 0]) * Matrix.CreateTranslation(Position);
}
}
public void UppdateMoveFoot()
{
LegPosition[0, 2] -= 0.25f;
LegPosition[1, 2] -= 0.25f;
LegPosition[2, 2] -= 0.05f;
meshLeg[0] = Matrix.CreateTranslation(new Vector3(0.0f, -0.25f, -3.4f)) * Matrix.CreateTranslation(Position.X, Position.Y, Position.Z + LegPosition[0, 2]);
meshLeg[1] = Matrix.CreateTranslation(new Vector3(0.0f, -0.25f, -3.4f)) * Matrix.CreateTranslation(Position.X, Position.Y, Position.Z + LegPosition[1, 2]);
meshLeg[2] = Matrix.CreateTranslation(new Vector3(0.0f, -0.25f, -3.4f)) * Matrix.CreateRotationX(LegPosition[2, 2]) * Matrix.CreateTranslation(Position);
}
