LÖVE

Maybe AMD is a no go, PriorBlue is there any way you can modifie the code so that it won't load this specific shader or part of the shader, maybe with a flag or something alike ?

Here is the error one of friends with AMD sent me.

'smooth' is a keyword in later GLSL versions. It sounds like the AMD compiler has a bug where it can't handle a variable named 'smooth' even in GLSL versions where it's not a keyword (and it's not a reserved keyword either.)

An easy fix would be to rename the variable.

this works, thanks slime.

Ok, at first a few answers:

Yes, its on my TODO list.

The light engine is completely separated from the physics and "drawing stuff" part, so you just have to synchronize the shadow bodys and lights with your game. When you update the light engine, all light/shadow information's will be generated in different canvases, which you can draw over or under your scene.

Yes, directional light will be included, soon.

Error
Cannot compile pixel shader code:
Line 2: error: Syntax error: "smooth" parse error

Yes, smooth is a keyword for ATI shaders. I have changed it to "lightSmooth".

So, here are the new things, i worked on:

My first normal shader calculation wasn't that good, so i watched a few other examples and rewrote him (I hope you can see the differences ).



I have finally integrated some options to generate normal maps. So you don't need to pixel them (this options will be extended in the future). It's for now possible to generate flat/gradient normal maps, convert height maps to normal maps and use(convert) the image itself as normal map (usually gives poor results).

Normal map gradient generation:


Height map to normal map generation:


Here some code examples: Shadow color and alpha (glass):


Code example: More informations can be found on the Wiki.

This is just so goood. Thank you so much for making this

What I found is that the shapes don't go into total darkness when cast into shadow. If you move the mouse away, things will get darker, but not when they are in shadow.

In order to make the "shadows" darker, you need to lower your values in the "yourVariableName.setAmbientColor(90,90,90)". If you want the shadow to make your boxes darker, you need to draw the boxes FIRST and then draw the shadow.

I know, the shadows are working with a stencil system at the moment, so i can't separate which object is over or under the shadow of another object. I hope i can change this in the future.

So and i polished the glow system, its now a little bit sharper:


And i added a glow functionality to standard circle/poly objects (Press "8" and "9" in the demo):


Here the code for the glow effects:

It's fantastic! Really wery awesome! Please, give me some advice about better way, to learn shaders?)
