# OpenGL Text Testing

Testing to see if I can get opengl text rendering using sfml as a font loader.

## Progress [(Album)](https://imgur.com/a/HulQLra)

Text loaded to a texture:

___

Text rendered as a single vertex array, one character per quad.

____

Text as row of text, except the image texture seems to be upsidedown flipped.

____

Finally worked out texture coords except a lot of characters were positioned incorrectly

Punctuation especially:

So added a bunch of hacky edge cases :/

Kinda works but idk prob is a better way:

## Building and Running

### Libraries

SFML and GLM are required.

These can be installed from your project manager. For example, on Debian/ Ubuntu:

```sh

sudo apt install libsfml-dev libglm-dev

```

If this is not possible (eg windows), you can install these manually from their respective websites:

https://www.sfml-dev.org/download.php

https://github.com/g-truc/glm/tags

### Linux

To build, at the root of the project:

```sh

sh scripts/build.sh

```

To run, at the root of the project:

```sh

sh scripts/run.sh

```

To build and run in release mode, simply add the `release` suffix:

```sh

sh scripts/build.sh release

sh scripts/run.sh release

```

You can also create a deployable build (that can be sent) by doing:

```sh

sh scripts/deploy.sh

```
