LÖVE

Posted: **Fri Feb 17, 2017 6:12 pm**

Hey,
Finally I can showcase my newest game, SquareWorld, a 2D sandbox game. It is the biggest game I've ever made and I am quite proud of it, even if the performance made a lot of trouble (previous text moved into a quote on the bottom).
It might become the first game I try to sell (on itch.io), so it must be further improved. But since I use an own launcher and downloader, a lot of complex shaders and an extreme VRAM intensive rendering sytem I am sure it will crash on some systems. So I want to ask you, if you could take a look on SquareWorld and tell me, if the a) game launches b) water is displayed and c) if the game crashes at some point.
If a error occurs somewhat like "Out of VRAM" or the game just quits, try to decrease settings in the main-menu options. Thanks for reading this

Controls: WASD movement, mouse to dig/build, E inventory, R recipe book, T achievements/tutorial tree, Q throw item away
To prevent dying, hide instantly after spawning.
If you spawn in the earth, press CTRL + 9 and then T to teleport (it will open the achievement tree too, will be fixed soon)

Download the installer here (Windows only, for now) (extract the zip and launch Lovum.exe, create yourself an account, select SquareWorld on the left and press Install)
https://www.dropbox.com/s/cdlnlsaaybxi8 ... m.zip?dl=0

Universal .love installer is causing trouble, see last post for more info.

Old topic:

Squareworld is a 2D sandbox game in a very early alpha phase. And it has a very big problem: it is slow. The rendering is mainly based on canvases and shaders (to transfer material data between canvases) which gives the game a huge range of graphical possibilities (reflections, bloom, leaves waving, different surfaces when smoothing the edges of blocks, ...), but also decreases it's performamce dramatically. Sadly I programmed the game on my mid-end PC, where the game works fine and then tested it on different PCs. The result: out of VRAM, lags, not supported canvas format and more. I will need to recreate the entirely drawing-section of my game, but before I start removing everything which is not important I want to ask you, how I should do the drawing of the scene? Currently I render everything once per chunk (64² tiles) on a few canvases (different layers + materials) which leads to intensive canvases usage. Is it a good idea to mainly use canvases? Are there other ways, like spritebatches? Have you experience with similar games? I attached the latest version of the game and a screenshot to show what results I want (EDIT: removed screenshot since the case is fixed). The game may crash.

Please, pay attention to the case of filenames. That is important.

Sorry for that, it should be fixed now.

I am going to simplify a lot of things, including this shader. But the part crashing in it is essential and I do not know why this error happens.
the shader receives a small canvas texture containing several (in future one) pixel per block which describes the liquids in my game (animation, shape, amount). Here is the raw code.

Code: Select all

//final render of liquids
//used in the final render engine

extern float time;
extern float size;
extern int cx;
extern int liquidRenderLimit;

extern Image liquidCanvas;
extern Image liquidTextures;
extern Image noise;

extern vec4 data_data[128]; 
extern vec4 data_colors[128]; 
extern float data_animSpeed[128];
extern int data_texture[128];

void effects(vec4 c, Image tex, vec2 tc, vec2 sc) {
	float rx = tc[0]*size;
	float ry = tc[1]*size - 0.5/32.0;
	int x = int(rx);
	int y = int(ry);
	float fx = fract(rx);
	float fy = fract(ry);
	
	vec4 color = vec4(0, 0, 0, 0);
	vec4 data = vec4(0, 0, 0, 0);
	
	float amount = 0;
	
	for (int i = 0; i < liquidRenderLimit; i++) {
		vec4 liquid = Texel(liquidCanvas, vec2(x/size, (y+float(i)/liquidRenderLimit)/size));
		if (liquid[1] == 0) {
			break;
		} else {
			amount = amount + liquid[0];
			int typ = int(fract(liquid[1]*2)*128)-1;
			float dist;
			float waveSize;
			float waveHeight;
			if (liquid[1] > 0.5) {
				if (liquid[2] == 0) {
					//cube
					dist = max(abs(fx-0.5)*2, abs(fy-0.5)*2);
					waveSize = sqrt(amount);
					waveHeight = amount*0.4;
				} else if (liquid[2] <= 1/128.0) {
					//full cube
					dist = 0;
					waveSize = 1;
					waveHeight = 0;
				} else {
					//waterfall
					dist = abs(fx-0.5)*2;
					waveSize = sqrt(amount);
					waveHeight = amount*0.4;
				}
			} else {
				//simple water
				dist = 1-fy;
				waveSize = amount;
				waveHeight = amount*0.4;
				if (fx > 0.5) {
					waveSize = waveSize * (1-fx)*2 + liquid[3]*(fx-0.5)*2;
				} else {
					waveSize = waveSize * fx*2 + liquid[2]*(0.5-fx)*2;
				}
			}
			if (dist <= waveSize - waveHeight * Texel(noise, vec2(cx*size+rx, time*data_animSpeed[typ]/8)/64).r) {
				int ty = int((data_texture[typ]-1)/4);
				color = Texel(liquidTextures, vec2(fx/4+(data_texture[typ]-1)-ty*4, fy/4+ty)) * data_colors[typ];
				data = data_data[typ];
			}
		}
	}
	
	if (color.a == 0) {
		discard;
	} else {
		love_Canvases[0] = color;
		love_Canvases[1] = data;
	}
}

As much as I know the limit of 128 different types sent via shader:send can't be exceeded.

Furthermore I came to the decision that changing the entirely drawing system is unhelpful and I want to remove as much features as possible, without destroying the base concepts of it. I calculated the minimum amount of needed canvases:
128 of 512*512 canvases
128 of 16*16 canvases
16 of 64*64 canvases
As I saw that some computers can't handle too big amount of canvases I want to ask before I try it: is this a acceptable amount?

Are you "okay" to show your PC (video card) specs/name?

P.S.
I'm no guru, but changing

Code: Select all

extern vec4 data_data[128]

to

Code: Select all

extern vec4 data_data[124]

worked like a charm for me.

GPU: Geforce GT 640 Synergy

Changing this value is no problem for me because the limit of 128 different liquids will never be reached, but it is still strange. Is there a limit of variables a shader can contain?

I think that depends on a driver.
According to this, my very old VCard have only 96 Shader processing units against over 350 in yours. Maybe driver for Linux compensates for some amount (or maybe my VCard is just a downgraded one). I'm no expert in HW.
I'll be able to test the game on Win10 x64 and tell you if it will run there w/o changes.
