[LibGDX] How to texturize a trinagle strip with an image?

Game Play & Game Design
#1

Hi to all! i’m creating a game with implemented box2D, and i want to create a dynamic ramdomized terrain like this :

how i have to do for texturize my point in a way like that in photos?
if you can a piece of code is apreciated XD

#2

Use quads, or increase the texture coords every 2 rectangles (like you are doing in the image).
Besides that, just draw them normally.

#3

I try and tell you if i do it right XD

#4

no, i’m not able to do this :frowning:
i have this code :

for(int i=0; i<colline; i++) {
				if(i != 0) {
					randomHeight = (float)Math.random()*hard;
					HillHeight -=randomHeight;
				}
				for(int j=0; j<HillSlices; j++) {
                    // Creo la posizione del punto del terreno
					vertici.add(new Vector2(j*distance+HillWidth*i, (float)(HillHeight+randomHeight*Math.cos(2*Math.PI/HillSlices*j))));
				}
				
				HillHeight += randomHeight;
		}

vertici il my array with all the points, but i really don’t know how to drow it in the rendere() with the texture, can somebody teach me how to do this?

  1. Why are you deacreasing height, and after the loop increasing it again?
  2. Why do you use multiple slices (using sin)?
  3. Math.rand() wont create nice noise, its okay for a test however (use simplex noise).
for(int i=0; i<colline; i++) {
    HillHeight -=randomHeight;
    nexthillheight = HillHeight - randomHeight2;

    corner_leftup = Vector2(HillWidth*i, HillHeight);
    corner_rightup = Vector2(HillWidth*(i+1), nexthillheight);
    corner_leftdown = Vector2(HillWidth*i, HillHeight+Height);
    corner_rightdown = Vector2(HillWidth*(i+1), nexthillheight+Height);
}

Draw using gl_triangles
Set texture coords accordingly (dont know how this is done in libgdx).
