I’m trying to get my invaders/enemies to move left to right then down like in the game space invaders. but I can’t for the life of me figure it out. Invader class https://pastebin.com/a14y0aHS Program class https://pastebin.com/aLHFM9ZW Not needed to change but here is the player class https://pastebin.com/CygjmEYr If there’s a better way to post my code her please let me know

i do not recommend the way you set the locations of your objects along with how you print them its very complicated, there's actually a better and an easier way

I just updated the pastebin links with the additions I added is it still bit messy! Like 3ish minutes ago

first, an object's location should not be an int alone in any 2d game, an object has a horizontal, and a vertical location we always represent them as x and y variables you either define an int X and an int Y for your player and invader class or make your own Struct that has X and Y fields and this is the recommended way we usually call the struct Vector2 second, the way where ur trying to print the objects is too complicated its actually simpler than that there is a method called Console.SetCursorPosition basically you use it to specify where in the command prompt window to print a string your invaders doesnt need to be stored in a 2d array, just a 1d array is enough, or a list

How would you go about making them come down after hitting the right side I also added the SetCursorPosition works great!

thats simple, iterate through each invader if one of them is on the right side, increment all the Y of all invaders by 1 seems your Location variable is still an int which isnt recommended and ur invaders field is still a 2d array

I see thank you I’ll try to figure that but I have one question how come when I run my code it closes after like 6 seconds is there a way for it to last longer?

TTheRanger

11/20/2023

did u update ur code?

SSpirant04

11/20/2023

Not yet but it always closes when the invaders hit the middle of the screen

TTheRanger

11/20/2023

well update and let me see

SSpirant04

Or when I move left or right immediately then it closes faster than that Fix it on program class line 62 I just put 8 instead of 5 that fixed that issue now to figure out to move down with out destroying everything I also need figure what I did do to make my player put in the middle I wanted it to be on left side like when I started where the invaders are Also I updated the links with additions

thats easy just increment y of each invader, or currentLine as u call it

SSpirant04

11/20/2023

If I couldn’t change the code I have now (example the invader class) how can I use the increment without the x and y solution 😦

I would use this!? Interesting

TTheRanger

11/20/2023

well, in ur code, Location represents the x and CurrentLine represents the y

SSpirant04

11/20/2023

I didn’t add the x and y in current line in the invader class that what I mean how to implement the downwards without changing it I know it’s not the ideal method to go about the invader class

TTheRanger

11/20/2023

ur not making any sense y represents the vertical position we just call it y your variable CurrentLine represents the vertical position you want the invaders to move down, ud have to change the value of CurrentLine
