> [https://editor.p5js.org/Nis\_Collect/sketches/U0p3GjOK1](https://editor.p5js.org/Nis_Collect/sketches/U0p3GjOK1) Given above is the link of my project. Someone please help me by reviewing my code and telling me that how can I confirm the collision of the player with the moving rectangles. Please provide me the code of only the lines which specifies the collision of the player and the moving blocks. I tried so many ways but I can’t figure it out. Please please help me.
