Learning C# - (Tile Based Game)

vvvv beta question
1

Hello

We are starting a project(me and @nissidis )
purpose of this project is to

  • get involved with c# codewriting
  • develop a tile based game logic integrated within vvvv

The first task was creating a node that produces an array(spread to be exact)
where, everytime we want(ex. if the right arrow is pressed)
all the lines move down (the last line is lost)
and a new line in the top is imported.

This is the code for a 8*8 array.

- region usings
using System;
using System.Collections.Generic;
using System.ComponentModel.Composition;

using VVVV.PluginInterfaces.V1;
using VVVV.PluginInterfaces.V2;
using VVVV.Utils.VColor;
using VVVV.Utils.VMath;

using VVVV.Core.Logging;
- endregion usings

namespace VVVV.Nodes
{
	#region PluginInfo
	[PluginInfo(Name = "Array_Edit", Category = "Value", Help = "Basic template with one value in/out", Tags = "")](PluginInfo(Name = "Array_Edit", Category = "Value", Help = "Basic template with one value in/out", Tags = ""))
	#endregion PluginInfo
	public class ValueArray_EditNode : IPluginEvaluate
	{
		#region fields & pins
		[Input("Input")](Input("Input"))
		ISpread<double> FInput;
		
		[Input("NewInput")](Input("NewInput"))
		ISpread<double> FNewInput;
	
		
		[Input("Add", IsBang = true)](Input("Add", IsBang = true))
		ISpread<bool> FAdd;
		
		[Input("GetArray", IsBang = true)](Input("GetArray", IsBang = true))
		ISpread<bool> FGet;

		[Output("Output")](Output("Output"))
		ISpread<double> FOutput;
		
		

		[Import()](Import())
		ILogger FLogger;
		
		
		
		#endregion fields & pins

				
		public void Evaluate(int SpreadMax)
		{
			var FHelper = new double[SpreadMax](SpreadMax);
			var Counter = new int();
			Counter = SpreadMax - 8;
			//8 is the number of columns in my spread
			
			FOutput.SliceCount = SpreadMax;
			if (FGet[0](0) == true)
			{
			      for (int i = 0; i < SpreadMax; i++)
				  {
				      FHelper[i](i) = FInput[i](i);
		
				      FOutput[i](i) = FHelper[i](i);
			      }	
				
            }
			if (FAdd[0](0) == true)
			{
				

			     
			     
				  for (int i = 0; i < SpreadMax-8; i++)
				      FOutput[i](i) = FOutput[i+8](i+8);
				
				  for (int i = 0;i < 8 ; i++)
				      FOutput[Counter +i](Counter +i) = FNewInput[i](i);
		    }
	     }
			  

			//FLogger.Log(LogType.Debug, "hi tty!");
		}
	}
  • How can we make the code more general(any way to find the number of columns in my spread, and not inserting it by hand)
  • Any other suggestions or comments are welcome.

Next task:
Create a node which replace each number of the array with a certain texture
and ouputs a single texture(simiral to cross transform).

We found it difficult (and maybe useless for now) to create
a c# code that produces a single texture by replacing array’s number with filepaths.


(red quad is our hero!)

*if someone can help on this it will be great(just to see the logic behind textures on c#)

So we made a patch where
*replace the numbers of the array with some simple texture(naming will help also for the collision part)
*Moving the array to the left is done by pressing right button

with 2 simple features
*Hero can jump + “gravity”(Up button)
*Collisions by creating new “Walkable Array” and checking certain conditions

we have made big progress and now we are trying to make
a node containing all the properties of a simple tile based game.
(i will post the plugins and the patch as soon as we fix all the bugs)

*i have a question on c# programming
i want to achieve the following:
if a button is pressed a variable starts to bang whit a certain (adjustable)
period.

thanks

you could start a Timer? or you sample the time from the IHDEHost:

code(lang=csharp):
Import()
IHDEHost FHDEHost;
…
FHDEHost.GetCurrentTime();

Here is our Bitmap Image Parser, created for the purpose of viewing and debugging Tile Maps, as soon as possible we will upload the BMPParser

The project continued, focused on pure c# code. We managed to reach a good visual result. Many problems generated during the process (basically on collision manipulation, and non-discrete Hero Positions coming from double accuracy on variables).

Recently i try to rebuild ,clean up the code, and fix some bugs. This is the result:

plugin can manipulate controlling hero with

  • 4 keys up/down/right/left
  • 3 keys jump(space)/right/left

The code still needs some cleaning.
If anyone interested, feel free to ask for it.
