hoi allemaal,

heb dit:

Code:

                if (preState.LeftButton == Microsoft.Xna.Framework.Input.ButtonState.Released)
                {

                }
                else
                {//Function for moving, scaling, rotating the objects.
                    if (CanEdit())
                    {
                        int xM = mouseState.X - preState.X;
                        int yM = mouseState.Y - preState.Y;
                        if (charDef.GetAnimation(f.AnimationBox.SelectedIndex).GetKeyFrame(f.FrameList.SelectedIndex).frameRef.partList.Count > selPart)
                        {
                            if (f == null)
                                MessageBox.Show("Is null");
                            new CharDef();
                            charDef.GetAnimation(f.AnimationBox.SelectedIndex).GetKeyFrame(f.FrameList.SelectedIndex).frameRef.partList[selPart].location +=
                                //charDef.GetFrame(selFrame).GetPart(selPart).location +=
                                new Vector2((float)xM / 2.0f, (float)yM / 2.0f);//Speed where u can move the objects

maar krijg bij deze regel:

Code:

 if (charDef.GetAnimation(f.AnimationBox.SelectedIndex).GetKeyFrame(f.FrameList.SelectedIndex).frameRef.partList.Count > selPart)

de volgende fout:

Object reference not set to an instance of an object.

Iemand een idee?

Alvast bedankt.

Dit kan aan veel dingen liggen

Code:

if (charDef.GetAnimation(f.AnimationBox.SelectedIndex).GetKeyFrame(f.FrameList.SelectedIndex).frameRef.partList.Count > selPart)

Misschien is f null
of
is er niks geselecteerd
als er niks geselecteerd is dan heeft "f.AnimationBox.SelectedIndex" een waarde van -1 .Als die waarde in de onderstaande methode wordt ingevoerd dan wordt er null geretourneerd.
Dus een leeg animation object dat nog niet geïnstantieerd is

Code:

public Animation GetAnimation(int idx)
        {
            //new CharDef();
            //new Animation();
            return (idx >= 0 ) ? animation[idx] : null;
        }

Dus zonder meer code is het moeilijk te zeggen wat de oorzaak is maar als ik zou moeten gokken dan zou ik zeggen dat het aan de Selectedindex ligt.

hoi

ja, heb nu dit:

index The name 'index' does not exist in the current context.

BIj deze regel:

Code:

                        if (charDef.GetAnimation(f.AnimationBox.SelectedIndex).GetKeyFrame(f.FrameList.SelectedIndex).frameRef.partList.Count > selPart)

hi

Code:

f.AnimationBox.SelectedIndex = -1

dit is wat ik zie bij deze regel:

Code:

                        if (charDef.GetAnimation(f.AnimationBox.SelectedIndex).GetKeyFrame(f.FrameList.SelectedIndex).frameRef.partList.Count > selPart)

Maar hoe los je nu dit op?

hi

Dit is de code van de AnimationBox:

Code:

 private void ChangeAnimation(object sender, EventArgs e)
        {
            if (AnimationBox.SelectedItem != null)
            {
                game.selAnim = AnimationBox.SelectedIndex;
                FrameList.DataSource = ((Animation)AnimationBox.SelectedItem).KeyFrame;
            }
        }

Object reference not set to an instance of an object.
