Tower Defense Game Tutorial with JavaScript & HTML Canvas

[@Gregor__Samsa]

I found out that the order of importing js files might cause the issue. Can you make sure that you import the waypoints.js before the index.js in the index.html?

i fell asleep, wake up to this playing in the morning what

[@daveinpublic]

At 15:00.. felt like the longest 5 minutes... How can you spend that long doing 1 thing?

[@JasonRobards2]

1:27:00 I don't give an intial x and y position with my constructor, since this information is in the waypoints array anyway. When changing the initial x position after going through the initialisation array, the code always writes the x position for the last element to all elements in the array. Can anyone explain why this could be? I guess it has something to do with how js refers to objects, but I am not well versed in this language. My intuition tells me this should work. const enemies = []; for (let i = 0; i < 10; i++) { enemies.push(new Enemy()); } for (let i = 0; i < 10; i++) { const xOffset = i * 150; enemies[i].position.x -= xOffset; console.log(enemies[i]); }

[@JasonRobards2]

This was my constructor and apparently this does not work. I don't know why. class Enemy { constructor() { this.waypointIndex = 0; this.position = waypoints[this.waypointIndex]; It kept overwriting so that all enemies in the array had the same position.

[@JasonRobards2]

This works: class Enemy { constructor() { this.waypointIndex = 0; this.position = { x: waypoints[this.waypointIndex].x, y: waypoints[this.waypointIndex].y }; I think the previous didn't work because it copied the label to this.position rather than the actual values, although I am not entirely sure what exactly happened. I am going to leave this little convo with myself in case someone else can make use of it :)

[@aionair77]

GO CHRIS!

[@NoThumb]

I see we all woke up to this 🤣

[@CallousCoder]

Wouldn't it be more sensible and robust to set objects in an array to null instead of splicing them out. And just check for a null (which you should always do anyways)? At least you don't need to worry about updating an array whilst looping through it. Either way this is easier than in C/C++ where you'd actually have to register which struct/object you want to free/delete. Also i noticed that projectile path is update every frame, so you have a "hear seeker" rock :D

[@babaakshay]

Great video! Could you please also make a video on how we could monetize these games built with Javascript? Maybe also release them on Android or IOS? I am really thinking of this as a full time job.
