try running

lime display windows -debug

in your project. it will show which Haxe compiler arguments are generated. it will include the path to Lime that is being used. I assume it won't be your fork's path.

The path there looks fine

i've never worked with a custom .haxelib directory that is outside of the global one, so I'm not sure how to suggest debugging that

i got rid of the custom

.haxelib

directory to see if that was the problem and it persists

That fork of lime is on my repo if you want to try to reproduce it https://github.com/EliteMasterEric/lime

I'm used to using

git clone

with

haxelib dev

instead of

haxelib git

, so there's another difference from how I do it

I just created a completely new Lime project (

haxelib run lime create Lime-HelloWorld

)

little-oxygen-79174

and get the same error when building that too

wait

if i build the lime project twice it works, but not a flixel project

what's the equivalent of

glGenBuffers

in lime?

in the cpp bindings I see this

Copy code

c
int lime_gl_create_buffer () {

    GLuint id = 0;
    glGenBuffers (1, &id);
    return id;

}

so it looks like you can create individual buffers with

gl.createBuffer ();

ohh

tall-teacher-57409

05/04/2023, 1:41 PM

Copy code

cpp
unsigned int VBO;
glGenBuffers(1, &VBO);

how would that look like?

can be a bit fun porting stuff from c to the lime bindings, I like to have lime source open for searching for the c calls

able-action-74275

05/04/2023, 1:43 PM

Copy code

hx
var vbo = gl.createBuffer();

tall-teacher-57409

05/04/2023, 1:43 PM

aight

tall-teacher-57409

05/04/2023, 1:54 PM

ok how do I now write glsl?

able-action-74275

05/04/2023, 1:55 PM

the shader code?

able-action-74275

05/04/2023, 1:55 PM

I'm not good with terminology

able-action-74275

05/04/2023, 1:55 PM

but guess you mean this

tall-teacher-57409

05/04/2023, 1:55 PM

yep

tall-teacher-57409

05/04/2023, 1:55 PM

ah yeah I see

tall-teacher-57409

05/04/2023, 1:56 PM

so just put it in a string

able-action-74275

05/04/2023, 1:56 PM

that's it

Copy code

hx
var gl = context.webgl;
                var vbo = gl.createBuffer();
                gl.bindBuffer(gl.ARRAY_BUFFER, vbo);
                gl.bufferData(gl.ARRAY_BUFFER, vertices, gl.STATIC_DRAW);

                var shader_src = "
                    #version 330 core\n
                            layout (location = 0) in vec3 aPos;\n

                            void main()\n
                            {\n
                                gl_Position = vec4(aPos.x, aPos.y, aPos.z, 1.0);\n
                            }\n
                ";

                var shader = gl.createShader(gl.VERTEX_SHADER);
                gl.shaderSource(shader, shader_src);
                gl.compileShader(shader);

Copy code

Source/Main.hx:21: characters 36-44 : Array<Float> should be lime.utils.ArrayBufferView
Source/Main.hx:21: characters 36-44 : ... For function argument 'srcData'

do I need to change my Array to ArrayBufferView (srcData is annotated as Dynamic though)

able-action-74275

05/04/2023, 2:21 PM

looks like you can do this for the ArrayBufferView

Copy code

new Float32Array (vertices)
