Handling enemy and hero collisions

- [Instructor] Hi there; welcome back to the video.…In the last video, we have created the enemy game object.…In this video, we're going to detect…collision between the hero and the enemy.…We begin with specifically defining…the objectsHitTest function, which checks the collision…between two given game objects.…Then, call the function to check the hero and the enemy.…If they colloid together,…we show the hit message in the console.…

Let's kickstart by opening the game-es6.js file…in the code editor.…In the world class, we define the objectsHitTest method.…It's different than our collision detection…between hero and the platform.…That logic specifically checks…if the hero is standing on the given object.…This function that we are implementing…is a generic collision detection that checks…if two given rectangle bounding box collide together.…

The core mathematic formula is to check both axes.…For each axis, the distance between two objects' position…should be less than half their width or height.…If both axes meet the collision, then it would mean…
