Hello,

When I try to start the game on Android from my Windows Desktop using:

adb shell am start -n " + id .. etc

I've noticed a md5 sum prefix on the activity name (default: Activity1). But because I'm generating the Visual Studio project file - among others - from templates, this md5 sum will change!

Is there any way I can query this md5 sum? Or turn it off?

Thanks!

Hi,

While I've managed to use Monogame from VSC IDE on macos, I feel like a lot is going on behind the scenes which I don't understand. And to allay this worry a bit, I want to build a game starting from nothing but the bare necessities (i.e., the Monogame dynamic libs), so that I get a better idea about what goes where. Coming from a macos/linux background, I would understand it much more if for instance, I could create all the files in the project directory myself, build it from the command line (calling C# compiler), and then run the game using mono. Is this possible? Any pointers on how I can go about doing this?

Thanks.

Sorry for my practice in English, I am French.

This is my actual method code:

	public void Compute(in GameTime gameTime, in EventHandler<DrawingEventArgs> drawing, in EventHandler<LightingEventArgs> lighting)

		// G-Buffer

		graphicsDevice.DepthStencilState = DepthStencilState.Default;
		graphicsDevice.SetRenderTargets(depthMap, albedoMap, normalMap, worldPositionMap);

		albedoMap = graphicsDevice.GetRenderTargets()[1].RenderTarget as RenderTarget2D;
		normalMap = graphicsDevice.GetRenderTargets()[2].RenderTarget as RenderTarget2D;
		worldPositionMap = graphicsDevice.GetRenderTargets()[3].RenderTarget as RenderTarget2D;

		// Ligh and Shadow

		graphicsDevice.SetRenderTargets(lightMap, shadowMap);
		graphicsDevice.Clear(Color.Transparent);
		graphicsDevice.BlendState = BlendState.Additive;

Hi all,

So I converted a win32 game to a win UWP got everything converted and running correctly except for one very annoying detail. If I roll the mouse up and up and up, it triggers the games title bar, and yep you guessed it if I go down and down up pops the start bar, I've got everything set to full screen as you would with a regular win32 app, so the question;
Is there a way to stop those bars from activating?
additional, my mouse routine uses delta's to place my game cursor really didn't want to re-write those again but I will if I have too.

Thanks peeps

So i just worked on this for the last i dunno 2 or 3 days and figured id post it as it is a bit different to a simplified orbit camera method.

The below camera code takes a Target Game Objects Matrix... one typically created with the Matrix.CreateWorld method as its target to orbit around.
It takes a distance from the target and a height above the target as well as a angle of rotation.

The target can however be in any orientation and the camera will stay aligned with its forward plane.
Basically if you have a rotated world matrix you can hover over it and move up or down or orbit around its center as if your just orbiting over a flat area that is still.

Basically its a cylindrical style to target camera.

You can alternately do things like flyby's at a specific height over a target that is moving and rotating in 3d space.

        Matrix OrbitAtHeightAroundTargetForward(Matrix target, float ForwardOrbitallRotation, float DistanceFromTarget, float zHeightAboveTarget)
        {
            float flip = -1; // quick fix think my model is upside down
            var targetAxisHeightOffset = target.Forward * zHeightAboveTarget;
            var targetPos = target.Translation; // yes this is intentional, see position.
            Matrix axisTransformation = target * Matrix.CreateFromAxisAngle(target.Forward, ForwardOrbitallRotation);
            // i don't think this can happen anymore now so its probably redundant.
            float proximityToGimblePointRight = Math.Abs(Vector3.Dot(axisTransformation.Right, target.Forward)); 
            var positionalDistanceOffset = Vector3.Lerp(axisTransformation.Right, axisTransformation.Up, proximityToGimblePointRight) * DistanceFromTarget;
            var position = targetPos + positionalDistanceOffset + targetAxisHeightOffset;
            var gimbleSmothingLookAtOffset = Vector3.Zero;
            if (DistanceFromTarget < .5f)
                gimbleSmothingLookAtOffset = (1f * flip * target.Forward + 2f * target.Left + 1f * target.Up) * .1f * (.5f - DistanceFromTarget);
            var toTarget = (targetPos + gimbleSmothingLookAtOffset) - position;
            var lookUp = flip * target.Forward;
            return Matrix.CreateWorld(position, toTarget, lookUp);
        }

I also made this one that just orbits the target it also stays with the target rotation.
It can offset the orbit so it can orbit over it in the full 360, but the height variable doesn't make much sense to use with this so i yanked it out.

        Matrix OrbitAroundTarget(Matrix target, float ForwardOrbitallRotation, float UpAxisRotation, float DistanceFromTarget)
        {
            float flip = -1; // quick fix
            var Target =  target * Matrix.CreateFromAxisAngle(target.Up, UpAxisRotation); // order matters its not commutative.
            var targetPos = Target.Translation; // yes this is intentional, see position.
            Matrix axisTransformation = Target * Matrix.CreateFromAxisAngle(Target.Forward, ForwardOrbitallRotation);
            float proximityToGimblePointRight = Math.Abs(Vector3.Dot(axisTransformation.Right, Target.Forward));
            var positionalDistanceOffset = Vector3.Lerp(axisTransformation.Right, axisTransformation.Up, proximityToGimblePointRight) * DistanceFromTarget;
            var position = targetPos + positionalDistanceOffset;
            var gimbleSmothingLookAtOffset = Vector3.Zero;
            if (DistanceFromTarget < .5f)
                gimbleSmothingLookAtOffset = (1f * flip * Target.Forward + 2f * Target.Left + 1f * Target.Up) * .1f * (.5f - DistanceFromTarget);
            var toTarget = (targetPos + gimbleSmothingLookAtOffset) - position;
            var lookUp = flip * Target.Forward; 
            return Matrix.CreateWorld(position, toTarget, lookUp);
        }

I'm trying to use a geometry shader to emulate water, but the programmable pipeline is ordered like so:

Which means that the geometry stage comes after the vertex stage. I wanted to ask, if I use the vertex stage to do the transformations, and use the geometry stage to do the normal calculations, where do I do the lighting?
PS. I will try to set the geometry shader using the underlying SharpDX.Direct3D11.Device to set the geometry shader and the variables.

We just spent the last day redoing the prologue for The Peacenet using new Peace Engine features such as the multicolored terminal and better audio and cutscene system. I like how it turned out, but I'd like to hear your opinions. Are there any things I could improve? Anything that needs changing? Let me know!

Funny thing is, at the end of the video, the abrupt ending is caused by the fact that Peace Engine actually crashed because the Peacenet Backend Protocol is multithreaded and two threads tried to touch the same thing on the server-side which causes problems. Pretty much an instant death sentence in C#. But that's what you get for doing Minecraft-like blended multiplayer where the singleplayer component is just a multiplayer server without an authentication layer and with additional singleplayer only features. We'll be redoing the protocol in the May 2018 Week 3 release though.

        if (enemy.Health <= 0)
          enemy.IsRemoved = true;
      }
    }
  }

The general gist is I loop around all my sprites twice. If they collide, then do something depending on the types of the sprites.

I have a feeling I'm going about it completely wrong.

Could I get some advice on how I could clean this up?

Cheers!

There are vs_4_0_level_9_0 and vs_4_0_level_9_1 ...
But most of the tutorials I found related to vs_1_1 or vs_3
I also read that there is a new syntax or new commands (a main method?) Is there somewhere a good DX9 to DX11 migration guide? (Or a good starter guide? Nothing good has been found on google yet :()

My question is simple: how can I support as many different types of joysticks as possible? Arcade sticks in particular have numerous amounts of boards you can use to create your stick, including the PS360+, which I use.

However, I notice I have to plug it in as 360 mode to get it to recognize. I also have an 8bitdo that I also have to plug in as XInput mode in order for it to recognize.

Is there some other library or class I should/can be using in order to have support for more devices, including Bluetooth controllers such as 8bitdo and PS4? I intend to support Windows 10, Linux, and macOS.
