In Topic: Creating Classic Goldsrc Based Engine

That is an obnoxiously large font :)

 

As for why you want to use the engine, its your own choice - but your time would probably just be better spent using Unity or something similar  - I know you mentioned liking old games, but nothing stopping you making an old game in an new engine.

 

I only did a quick google search, but check out https://developer.valvesoftware.com/wiki/Goldsource at a glance, it appears to have links to what you what


In Topic: 2D Plain/layer Shift Game Play Mechanics

Unfortunate timing of me reading this post.. I need to stop killing the end of my day with this forum :)

 

Ive never used melonJS, but from looking at the homepage, it mentions 'Multiple layers with parallax scrolling' I also see mentions of z sorting

 

This would suggest there is someway to set up multiple layers - ie one layer for each map, and even if there was a restriction on how many tilemaps you could load - you could always store the background map in the first half of the array, and the background map in the second half. Obviously not the most ideal solution, but something that may work as a quick suggestion

 

It might just be easier to use another one of the engines you have mentioned - but just thought id mention the above if you felt like melonJS is something you like, as to not prematurely drop it

Hi

 

This just looks like there are two tilemaps at play, so using one for a forground, and one for a background.

 

forground[10][20];

background[20][40];

 

player_position_forgroundX = player_postionX / 20;

player_position_backgroundX = player_postionX / 40;

 

player_position_forgroundY = player_postionY / 10;

player_position_backgroundY = player_postionY / 20;

 

and when the witch occurs you are just using a smaller image / scaled image, and display it on the toggled map.

 

This is an overly basic explanation, as im just finished work now and about to run out the door :)


In Topic: Generate terrain once given the heightmap

The pixelation is probably to do with your texture setup, have a look here at the section describing GL_NEAREAST and GL_LINEAR http://learnopengl.com/#!Getting-started/Textures ( or just at the whole site in general, its a great resource :) )

Hi,

 

It can be hard to tell if your calculations are a bit off (cant do them in my head :) ) or what affect the 'up' value is having against your z value. But id find something like the following a little easier, altough not tested

 

      float scale = 10.f;
      float height = (float)img.data[i] / 255.0f;
      
      for( int z = 0; z < img.height; z++ )
      {
          for( int x = 0; z < img.width; x++ )
          {            
            model->vertices.push_back(glm::vec3(  x    * scale, height * scale,  z    * scale ));
            model->vertices.push_back(glm::vec3( (x+1) * scale, height * scale,  z    * scale ));
            model->vertices.push_back(glm::vec3( (x+1) * scale, height * scale, (z+1) * scale ));
            
            model->vertices.push_back(glm::vec3(  x    * scale, height * scale,  z    * scale ));
            model->vertices.push_back(glm::vec3(  x    * scale, height * scale, (z+1) * scale ));
            model->vertices.push_back(glm::vec3( (z+1) * scale, height * scale, (z+1) * scale ));
          }
      }

 

As for ruling out problems with your own, try slap glPolygonMode( GL_FRONT, GL_LINE ); above your rendering, and it will display it as a wiremesh - you should then atleast see how your triangles look beneath the surface.

 

Maybe just try drawing it all using points first - get the calculations correct - and then move onto triangles when you are happy. you can make the point size bigger using glPointSize(5.f);

 

Sorry i cant help anymore at the minute, but keep at it!
