### Re: Shader variables - documentaiton and get the transformed vertext position

Thanks for such an indepth write up!
I'm going to have to find a note book like im in class lol
Will give this a proper read over weekend - when work code isnt in my brain trying to push out game code

### Re: body:getposition with multiple shapes

Hey guys, ive added another demo. So I build 4 shapes: local shape = love.physics.newRectangleShape(0, -width, width, height) local fix = love.physics.newFixture(player, shape, 1) local shape = love.physics.newRectangleShape(8, -height, width/2, height/4) local fix = love.physics.newFixture(player, ...

### Re: body:getposition with multiple shapes

I think it would be more strange if the body's position changed as you added fixtures to it, or if the order that you added them in mattered. What if you did that at runtime? All of a sudden all your calculations could be broken. The way it is now, it only does exactly what you tell it to. Maybe yo...

### Re: body:getposition with multiple shapes

My understanding is that zell2002 started with a plain WxH rectangle for the player, and when he noticed issues when hitting seams (a frequent problem), he just tried to make the base rounded without altering the rest of the program. This meant the centre had to stay in the same place and everythin...

### Re: Shader variables - documentaiton and get the transformed vertext position

Thank you for that explanation! Makes a lot more sense. The transform_projectio variable passed in, that is a mat4, are you saying each item that you mention "It combines the transformation matrix that transforms LÖVE vertices according to the given scale, rotation, translation and shear" as a seper...

### Re: Shader variables - documentaiton and get the transformed vertext position

Thanks for all that, I had no idea thats how it behaved. Its pretty neat being able to do: vec4 bar = vec4(0,1,0,1); vec2 foo = bar.xy; mat4 TransformProjectionMatrix The combined transform and projection matrices. Used as the transform_projection argument to the vertex shader position function. So ...

### Re: Shader variables - documentaiton and get the transformed vertext position

Cheers for that. I did look over that wiki page before posting, as I said I'm unsure what the items are in mat4 list - as there's a possible 4 different objects in there?

Thanks for explaining the transformation, seems very obvious now,

### Shader variables - documentaiton and get the transformed vertext position

Hey guys, https://love2d.org/wiki/Shader_Variables From there, I don't fully get how to access the global variables. Are there any examples anywhere ? Also the variable types, there's no explicit write up? vec4 I assume has .x and .y, but I dont know what the 3rd and 4th are. I assume z and then.......
