# V_sokol_gp

a V wrapper for the sokol_gp library 

# Sokol_gp

Sokol_gp is a 2d rendering library for Sokol that has many optimations to it like batch rendering plus it is super easy to use and setup 

# install

`v install mohamedLT.sokolgp`

# supported platforms 

basically, it runs where Sokol runs 

for android you can use vab 

# Example :

```

import gg

import sokol

import sokol.sapp

import mohamedlt.sokolgp 

import sokol.gfx

import math 

fn frame(s voidptr) {

    width := sapp.width() 

    height := sapp.height()

    ratio := width/f32(height)

    sokolgp.begin(width, height)

    sokolgp.viewport(0, 0, width, height)

    sokolgp.project(-ratio, ratio, 1.0, -1.0)

    sokolgp.set_color(0.1, 0.1, 0.1, 1.0)

    sokolgp.clear()

    time := f32(sapp.frame_count() * sapp.frame_duration())

    r := math.sinf(time)*0.5+0.5

    g := math.cosf(time)*0.5+0.5

    sokolgp.set_color(r, g, 0.3, 1.0)

    sokolgp.rotate_at(time, 0.0, 0.0)

    sokolgp.draw_filled_rect(-0.5, -0.5, 1.0, 1.0)

    pass_action := gfx.PassAction{}

    gfx.begin_default_pass(&pass_action, width, height)

    sokolgp.flush()

    sokolgp.end()

    gfx.end_pass()

    gfx.commit()

}

fn init(s voidptr) {

    sgdesc := sapp.create_desc() 

    gfx.setup(&sgdesc)

    if !gfx.is_valid() {

        println("Failed to create Sokol GFX context!\n")

        exit(-1)

    }

    sgpdesc := sokolgp.Desc{}

    sokolgp.setup(&sgpdesc)

    if !sokolgp.is_valid() {

        println("Failed to create Sokol GP context:  ${sokolgp.get_error_message(sokolgp.get_last_error())}\n")

        exit(-1)

    }

}
