OPESV Engine

=============

Orthogonal Perspective Elevation Side View Game Engine.

A simplistic 2d game plataform shooter boiler plate.

OpesV-Engine aims to provide a simplistic platform for 2d games. 

This is **not** production ready and probably never will. This is *Work in Progress*, plus it's done only for enterteinment purposes, so probably it wont be useful to you... yet.

It uses [ebiten](https://ebiten.org/) game library. The images  in the demo game belongs to that project, it is their default image samples.

What can be done with it for now:

    - create a tile based map.

    - control a player that jumps and shoot his gun.

    - control enemies that fiercely tries to kill our hero.

    - collision detection.

    - guns can be changed, and can be parametrized (damage, rate of fire, range, etc)

To be done:

    - looking for a performant way to flip images when player changes direction.

    - allow maps larger than screen.

    - make usage of different tile sizes easier.

    - better AI for npcs.

    - different actions for NPCs (now they just care about one thing: Kill you).

    - a score panel.

    - (SOLVED) still get stuck on the walls sometimes...

    - documentation.

Running the example:

```bash

    git clone https://github.com/gsteixeira/opesvengine

    cd opesvengine/

    # get dependencies

    go mod tidy

    go run sample/demo.go

```

Create a sprite (static object):

```go

    // you can specify an image or use the images described in ebiten

    img := opesvengine.Get_img_from_file("some_image.png")

    // create the sprite

    foo := opesvengine.NewSprite(10, 10, img, false)

```

Create a Character (a live, movable object):

```go

    // specify an image

    img := opesvengine.Get_img_from_file("some_image.png")

    // set initial parameters

    pos_x := 0

    pos_y := 0

    width := 16

    height := 32

    // create the character

    player := opesvengine.NewCharacter(pos_x, pos_y, width, height, img)

```
