SDL2 side project, let's make a game engine~ (and maybe a game) SDL2: https://www.libsdl.org
Using SDL2, we shall recreate a 2D top-down sprite based RPG.
The combat will not be a turn-base system but rather the player will attack in real time similar to the old Zelda games.
The player wakes up nearby in a forest and is found by a villager that lives on the outskirts of town.
The player repays the villager's hospitality by gathering resources from the forest and dungeons to rebuild the house.
Villager wants to open a shop for exotic items so the player will need to trade and barter with the townsfolks.
Player will try to survive day to day repaying debt to outskirt villager / Run the store.
By nature a game engine must require a main game loop in which the execution will run repeatedly until user dictates exit
Two main parts that make up the game loop are:
1) Render -> Allows us to display images and stuff on the screen
2) Logic -> Dictates how those objects interact with each other
Logic-wise, the Game Requirements will dictate how we code the logic but for now we focus on the Render part in this section
- Display Background image (for world map)
- Allow for user to get Tick (time from the last update frame call in ms)
- Display static object (stationary object above the background image)
- Display dynamic objects (objects dictated by code that can move around the screen)
- Cull dynamic objects (used for displaying/hiding object on the Z-axis, for example behind a tree, or rock, or infront)
- Basic Collision Detection for Dynamic objects and static objects`
- A world the player can move around in along with mini-area's (ie. houses, caves, etc...)
- Save and Load System
- Player Inventory and equipment (Player UI ?)
- Barter and Trade system
- Non-player character dialogue and interface system
- Enemies to fight
- Items and loot drop
- Implement a scripting system for super moddability to add objects
- Implement world editor of some sort, allows for editing tile maps?
