Add a game timer

2022-04-02T03:23:01+00:00

This adds a delta time that ensures that everything moves at the same
speed regardless of framerate or system.

Store train objects in a unique_ptr

2022-03-31T03:48:07+00:00

The trains were being destructed after leaving the scope of the
addVehicle function. This change makes sure the trains stay allocated
for the entire lifetime of the level.

Fixes #2

Fix sprite sorting when rendering the level

2022-03-29T22:29:56+00:00

This fixes a misuse of std::find_if and vector iterators. Previously,
the first vehicle in the currently drawing tile would be drawn, and then
every other vehicle would be drawn regardless of position.

Return a reference instead of a pointer in addVehicle()

Fix SDL include path in window.cpp

2022-03-27T03:05:21+00:00

Add missing #includes for find_if and ceil

2022-03-27T02:42:22+00:00

Implement sprite depth sorting

2022-03-26T17:50:51+00:00

This algorithm draws the level in two passes; the ground and rail tiles
are drawn first, then the train cars and walls. This method isn't
perfect, but it'll do for now.

Add a header to the level file format

2022-03-24T18:01:09+00:00

Create new trains on right click instead of moving the existing train

2022-03-24T15:17:45+00:00

Don't create a copy of the train graphics per vehicle
