bufferutil | WebSocket buffer utils | Websocket library

As I researched a lot and did not find a solution to this issue as it's occurring only on the newer version of the animation package.

I tried the below versions:

• 13.2.4 (Latest one) throwing same es error

• 13.2.3 throwing same es error

• 13.2.2 throwing same es error

• 13.2.1 throwing same es error

• 13.2.0 working without error.

So I think for a temporary fix you should update your package.json by pointing to a specific version of this npm like below.

In your updateShaderParameters() method your checking for !=1 it should be !=-1 since windowSize location would be 1.
If your checking for 1, it will never get set.
This could be an oversight or a mistype at the end. Happens to the best of us.

Remove the call to matrixBuffer.flip()

To know why your code does not work requires you to know what Buffer.flip() (called via your FloatBuffer.flip()) does exactly:

Flips this buffer. The limit is set to the current position and then the position is set to zero. If the mark is defined then it is discarded.

(bold highlight by me).

You know, a NIO Buffer has a position, mark, limit and capacity. When you create a new NIO Buffer e.g. via BufferUtils.createFloatBuffer(size) then you will be given a FloatBuffer that is a view of an underlying direct ByteBuffer which has a capacity of size, a limit of size, a position of 0 and no mark set.

Usually, relative NIO Buffer put operations in the JDK will increment the buffer's position. However, JOML's Matrix/Vector.get(Buffer) won't do this, much like all LWJGL/OpenGL methods which take a NIO Buffer as parameter, such as GL15.glBufferData(...).

So, when you call Matrix4f.get(FloatBuffer) then the position of the supplied Buffer will not be modified and therefore, calling .flip() on that buffer afterwards will set the limit of the buffer to where the buffer's position was (likely 0).

The next thing you need to know is that LWJGL methods that take a NIO Buffer will use the buffer's .remaining() (which is .limit() - .position()) to determine the argument value to any size/length parameters for the underlying native OpenGL function call. In the case of glUniformMatrix4fv() with native signature:

void glUniformMatrix4fv(GLint location, GLsizei count, GLboolean transpose, const GLfloat *value);

LWJGL will infer the value for the count parameter based on the .remaining() / 16 of the supplied NIO Buffer. Since your Buffer likely has a .remaining() of 0 (due to the .flip() call when said buffer had a position of 0 - due to Matrix4f.get(FloatBuffer) not having incremented the position) the supplied OpenGL function argument will be 0, which will cause a noop in this case.

I needed to install the following missing dependencies:

• bufferutil
• utf-8-validate

A simple yarn add bufferutil utf-8-validate fixed it for me. This is mentioned in docs for socket.io-client package or socket.io official documentation website.

This did fix builds on my PC (windows) but I could not get the same thing running on mac. I tried deleting node_modules and yarn.lock, re-running yarn.

Finally I had to go through the CDN route.

This is how I did it:

1. Move the socket initialisation logic in a function.

Install / Re-install Python and make sure it is in your $Path

The problem was that, the old bcrypt-as-promised package used .catch block to handle invalid password, but in the new bcrypt, everything needs to be handled in the .then block, based on the result.

Handling invalid password in the then block solved my issue.

Firstly, call the GL30.glVertexAttribPointer(1, 3, GL30.GL_FLOAT, false, 0, 0); (for the colour buffer) before calling GL20.glEnableVertexAttribArray(1); (you should allocate your attributes before enabling the attribute arrays).

Secondly, your draw function incorrect:

When rendering,

1. Bind your shader (GL20.glUseProgram(program))

2. Bind your VAO (GL30.glBindVertexArray(VAO))

3. Setup your shader uniforms (I guess your not up to this step yet, so dont worry for now)

4. Enable your vertex attribute arrays (GL30.glEnableVertexAttribArray(number)) - Calling this method for every buffer slot allocated and EVERY TIME YOU RENDER (not just when you set up the buffers).

5. Render / call the draw function

6. Disable your vertex attribute arrays (GL30.glDisableVertexAttribArray(number)) - Calling this method for every buffer slot allocated and again, EVERY TIME YOU RENDER

7. Unbind VAO (GL30.glBindVertexArray(0))

8. Unbind Shader (GL20.glUseProgram(0))

In webpack.mix.js Simply remove loader: 'url-loader' it worked for me

Your code doesn't really make sense. If you haven't already linked shaderProgramID, then you cannot call glGetAttribLocation. And if you have linked shaderProgramID, then calls to glBindAttribLocation will do nothing, since they only have an effect on subsequent linking operations.

Lastly, if you already have a location for the attribute (that is, if glGetAttribLocation worked), there is no point in calling glBindAttribLocation, since you already know the answer. So there is never any point to calling both get and bind on the same program ever. Either you correctly told OpenGL what attribute location to use (and therefore have no reason to ask later) or you want to query the attribute location (and therefore don't want to specify it).

A linked GLSL program contains a mapping between attribute names and locations. You can define this mapping in various ways. But if you don't provide an attribute with a location before you link the program, then OpenGL will assign that attribute a location. And once that happens, there is nothing you can do about it for that program.

The best way to set the attribute location is from within the shader, with a layout(location = #) specifier. That way, you don't have to query anything from glGetAttribLocation, and there's no need to use glBindAttribLocation. Pick a standard convention for attribute indices and go from there. For example, you could say that standard colors all use attribute 2. You don't need to ask the program what attribute index their color is in; you know it's 2.

This is ultimately no different from having a convention for naming attributes. Your above code assumes that the attributes are named "position" and "colour". If the maker of a shader uses the wrong names, your code won't work. Using a number instead of a name is no different, and you get to avoid asking for the attribute location.
