Of course, if the map is large this doesn't really solve the problem - and some systems don't have a very generous limit on how big a texture can be. One simple technique consists of pre-rendering the map in a canvas on its own (when using the Canvas API) or on a texture (when using WebGL), so tiles don't need to be re-drawn every frame and rendering can be done in just one blitting operation. The first approach, as discussed above, is to only draw tiles that will be visible. Usually, some techniques need to be implemented so scrolling can be smooth.

The tile atlasĭrawing scrolling tile maps can take a toll on performance. Think about any game that uses regularly repeating squares of background, and you'll probably find it uses tilemaps. Some popular games that use this technique are Super Mario Bros, Pacman, Zelda: Link's Awakening, Starcraft, and Sim City 2000. This set of articles covers the basics of creating tile maps using JavaScript and Canvas (although the same high level techniques could be used in any programming language.)īesides the performance gains, tilemaps can also be mapped to a logical grid, which can be used in other ways inside the game logic (for example creating a path-finding graph, or handling collisions) or to create a level editor. This results in performance and memory usage gains - big image files containing entire level maps are not needed, as they are constructed by small images or image fragments multiple times. Throughout the process, I played the map multiple times to test it and ensure that everything worked as it was supposed to.Tilemaps are a very popular technique in 2D game development, consisting of building the game world or level map out of small, regular-shaped images called tiles. Next, I focused on the aliens, going about their scripting in a similar manner to the player, following which I created logic and scripted the gameplay systems like increasing difficulty with consecutive waves, alien spawn points and item pickups.įinally, I finished by using UMG to showcase the HUD and sound effects for better immersion. This project brings together a lot of new things that I learned as well as an opportunity to explore and reinforce what I've already done before and create something to connect it to fully form a game.įirst up, was the setup of the base level, following which I created the player blueprint and each of its functions, from movement and inputs, to shooting, animating the character mesh with blendspace and then using a statemachine to nicely transition between the animations and events such as Player death. As I went, I started making small and simple protoypes myself.

I started my unreal journey by simply watching some tutorials. This is a simple showcase of a variety of blueprints and UE4 systems running together to showcase each of the mechanics and features I have built to build this project. I enjoyed making the player and aliens come to life by taking advantage of efficient and easy to use tools available at my disposal thanks to the power of UE4. As a fan of sci-fi and aliens, this was a fun way to learn and exercise my skills with the Unreal engine.
