First off, if this isn't the right place for this question, then I apologize.
Anyway, my question is two-fold. I'm doing work in DirectX 9 on Visual Studio in Visual C# (but that can change if truly necessary) to get force feedback effects on a Sidewinder joystick. As it is I have pre-loaded vibration effects (like gun recoil, chainsaw buzz, etc) playing like a charm, and have recently been working with ConstantForce, and after much finagling I did actually get it to do something like what it's supposed to do. But it has caused two things:
1) How do I get it to go in different directions? I know that there is the "eff.SetDirection(new int[axis.Length]);" condition, and I know that replacing axis.Length with 0 will cause the force vector to push forward, but everything else causes it to push left. I really need control over the direction of the force vector.
2) Why is it that the same code when compiled in Visual Studio .Net results in a different sensation than when compiled in Visual Studio 2005? Like, noticiably different!
Hopefully someone can help me out here. I would appreciate it. Below I'll put the pertinent code for all to see and enjoy.
Note: The trackbar1, 2, etc. values are just trackbar form elements I put into the design so that I could change the values for Gain, Magnitude, etc. on the fly.
if(checkBox2.Checked)
{
foreach (EffectInformation ei in device.GetEffects(EffectType.All))
{
//If the joystick supports ConstantForce, then apply it.
if (DInputHelper.GetTypeCode(ei.EffectType) == (int)EffectType.ConstantForce)
{
Effect eff = new Effect();
// Allocate some memory for
//directions and axis.
eff.SetDirection(new int[0]); // new int[0] = forward zomg, everything else = left... hmmm
eff.SetAxes(axis);
eff.EffectType = EffectType.ConstantForce;
eff.ConditionStruct = new Condition[axis.Length];
eff.Constant = new ConstantForce();
eff.Constant.Magnitude = trackBar1.Value;
eff.Gain = trackBar2.Value;
eff.SamplePeriod = trackBar3.Value;
eff.Duration = trackBar4.Value;
eff.TriggerRepeatInterval = trackBar5.Value;
eff.TriggerButton = (int)Microsoft.DirectX.DirectInput.Button.NoTrigger;
eff.Flags = EffectFlags.ObjectOffsets | EffectFlags.Cartesian;
eff.UsesEnvelope = false;
// Create the effect, using the passed in guid.
eo = new EffectObject(ei.EffectGuid, eff, device);
eo.Download();
eo.Start(1,EffectStartFlags.NoDownload);
label2.Text = "Effect GUID: " + eo.EffectGuid.ToString();
label2.Text += "\n Is Effect Playing?: " + eo.EffectStatus.Playing.ToString();
label2.Text += "\n Effect Type: " + eff.EffectType.ToString();
label2.Text += "\n Axis Length: " + axis.Length;
label2.Text += "\n Gain: " + trackBar2.Value.ToString();
label2.Text += "\n Magnitude: " + trackBar1.Value.ToString();
label2.Text += "\n Sample Period: " + trackBar3.Value.ToString();
}
}
if (eo == null)
{
throw new Exception("ConstantForce is not supported.");
}
}
