The Project focuses on designing and implementing a VGA-based game using SystemVerilog on the DE-1O lite board. Our primary objective of the project is to create an engaging and educational gaming experience and provide a learning experience through the game development process, implementing the concepts learned in classes and labs. It also showcases the efforts in logic designing, real-time dynamic visual feedback, focusing on the details, providing clarity on clock working, while addressing the problems faced on the way to deliver a gaming experience on the FPGA hardware. By utilising VGA display, HEX display, KEY[0], KEY[1], SW[0:9], LEDR[0:9] as well as the clock, our game provides an immersive experience in a dynamic virtual world filled with challenges and rewards
● Users select levels by activating the respective switches which are SW[0] for Level 1, SW[1] for Level 2, and SW[2] for Level 3, and pressing KEY[0]. The text turns to yellow when a level is selected. The text displayed along with the colours are methods via pixel logic and rendering.
● Platform movement logic - When the counter reaches the value of 1000000, it resets zero and checks the position of platform 1. Depending on the position, the direction of movement is adjusted accordingly. If the position is above or equal to 420, it changes direction. The platform’s position is updated based on the direction of movement.
● Player movement logic - It checks if a counter has reached a threshold, and then resets the counter. Depending on the direction of the player character and its position, the code adjusts the position of the player within the screen bounds. The direction changes according to the continuous movement within screen limits.
● Jumping behaviour and adjust ground- The jump height has been set to 50 pixels. A counter tracks the duration of the jump and adjusts the player’s vertical position based on the ascending or descending phase of the jump. If the player is about to land on the platform, the position is adjusted accordingly and the ground is updated setting it as a new ground. If the player is not jumping and the KEY[1] is pressed, the character is set to jump in its place. The code makes sure that the player falls when no platform is detected. It tracks the state of the jump button. If at the bottom, the ground level is 450
● Coin Collection and collision - This part of the code checks if the coin is visible on screen and the player’s position overlaps with the coin position. If a collision is detected, the coin’s visibility is set to 0 which indicates the coin has been selected and the coin counter is increased to keep track of the collected coin and display it on the HEX[3] and HEX[4].
● Random coins generating logic - This part of the code checks if all the coins are collected, it generates more coins by resetting their positions to make them visible again. New positions are determined by randomizerCount and its variants.
● Red platform Collision and reset the level - When the player collides with a red platform, the game over screen is rendered from the second always block. It resets the level by resetting the position and movement directions of all platforms and player characters to their starting state. It reset the counters and flags related to jumping and movement. The platforms and player is set to their starting state and randomizer counters are reset to generate new positions for coins.
● Counter and High score display on HEX displays - The counter decrements from 45 to 0 every second based on the clock. When the count reaches zero, it indicates the end of the countdown, the flag is set to 1. The code also converts the second count into a two-digit pattern for display on the HEX display.
● Image rendering, pixel manipulation, and VGA display - This part of the code renders various elements including the player, platform, and cons with different colors based on the position. If the game-over conditions are met, it displays “GAME OVER” on the screen with a black background. It also showcases different colour backgrounds for different levels and the main page and game over the page. RESULTS
● The resources we used was the lab 5 file vga_controller.v to use for connecting to the monitor. We used a monitor with a vga connection as well as the De-10 light board.
