2D Collision

Collision is handled by firing rays out of the box collider every frame in the directions of movement (up, down, left or right) with length of the delta movement of that frame. If one or more rays collide with an obstacle then a collision is triggered. The number of rays can be adjusted, with more rays giving greater collision accuracy on more complex shaped obstacles.

Variable Jump Heights

The jump arc is split into 3 parts. The first part of the arc has a constant velocity for as long as the jump button is pressed (up to a certain point). The second arc is designed to rapidly decrease the upward momentum into a slower fall which is arc 3. This gives the platforming a tight and precise feel.

The minimum and maximum jump height can be adjusted along with some other settings such as the time taken to get to the jump apex for precise tuning. This then calculates the required jump velocity and gravity values on runtime.

Wall Jumping

On collision with a wall in the air, the player "sticks" to the wall and slowly slides down. There are 3 ways in which the player can jump from the wall.

Direction held towards the wall: Jump with more height and less horizontal movement. This allows for easy wall climbing.

Direction held away from the wall: Jump with less height and more horizontal movement.

No Direction held: Jump with less height and less horizontal movement.

Custom Sprites and Animations

I drew numerous pixel animations for this project. This includes 2 different attack animations which don't have much use since enemies haven't been added yet.
