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)
    }
}



struct App {
mut:
    gg          &gg.Context = unsafe { nil }
}

[console]
fn main() {
    mut app := &App{
        gg: 0
    }

    app.gg = gg.new_context(
        width: 600
        height: 600
