I am trying to create a simple game for android, to start i am trying to make the square move down the y axis but the way i am doing it dosent move the square at all and i cant find any tutorials for GLES20
The on draw frame function in the render class updates the users position based on accleration dew to gravity, gets the transform matrix from the user class which is used to move the square down, then the program draws it.
All that happens is that the square is drawn, no motion happens
public void onDrawFrame(GL10 gl)
{
user.update(0.0, phy.AccelerationDewToGravity);
GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT | GLES20.GL_DEPTH_BUFFER_BIT); // Re draws black background
GLES20.glVertexAttribPointer(maPositionHandle, 3, GLES20.GL_FLOAT, false, 12, user.SquareVB);//triangleVB);
GLES20.glEnableVertexAttribArray(maPositionHandle);
GLES20.glUniformMatrix4fv(maPositionHandle, 1, false, user.getTransformMatrix(), 0);
GLES20.glDrawArrays(GLES20.GL_TRIANGLE_STRIP, 0, 4);
}
The update function in the player class is
public void update(double vh, double vv)
{
Vh += vh; // Increase horrzontal Velosity
Vv += vv; // Increase vertical velosity
//Matrix.translateM(mMMatrix, 0, (int)Vh, (int)Vv, 0);
Matrix.translateM(mMMatrix, 0, mMMatrix, 0, (float)Vh, (float)Vv, 0);
}
