Artillery

In this game, 2 or more players take turns attempting to hit the other player(s) with a tank shell. The objective of the game is to be the last tank standing. Players must perfect their aim since tank shells are heavy and are heavily influenced by gravity. Players must also account for the hilly terrain and may need to clear portions of terrain away to get a better shot.

Players may navigate their tank anywhere on the terrain and shoot. Players may also be moved when a tank shell from an enemy clears terrain below them. Another caveat of this game is that tank shells not only take hit points away from players, but also destroy pieces of terrain in the vicinity of the blast impact.

Demo

In this demo, you can see the functionality of aiming with your mouse. The game provides a laser that points in the direction of the barrel. When a user presses the SPACE bar, the currently active tank shoots a bullet in the direction the mouse is pointing at. If the bullet hits a tank, that tank loses an amount of hitpoints that is proportional to the magnitude of the bullet's velocity. If the bullet hits the ground, some terrain is blown up in a crater. The crater's radius is also proportional to the magnitude of the bullet's velocity.

Players also have the option to use aim assistance. Aim assistance predicts the parabolic path of the bullet, if fired at any instant. The menu displayed when the game is paused allows users to configure aim assistance for each of the active players.

Building and Running

To run the game, you must first install cmake. If you have homebrew, you can do so by simply running brew install cmake from a command line. Alternatively, you can follow these instructions to install cmake.

You must install Cinder for this game. You can find instructions to do so here. Next, you must clone this repository in a subdirectory of the Cinder directory named my-projects.

Then, navigate to the project root directory and create an empty directory, ideally named build (any name will suffice). I will refer to this directory as <build-dir>. If you have opened the project in CLion, you will not need to do this. CLion will have already created a build directory named cmake-build-debug. Next, run the following command in a command line: cmake --build <path-to-project-root>/<build-dir> --target artillery-main -- -j 3.

Next, navigate to the build output directory. If you are on a Mac, this will be <build-dir>/Debug/artillery-main/artillery-main.app/Contents/MacOS/. Now, simply run the executable named artillery-main! It will be located in the build output directory you found above.
