TEMPEST GYRUSS

Get help using Construct 2

Post » Sun May 11, 2014 4:40 am

hello guys: i'm making a game like the 1980s game Tempest / Gyruss and i have the players ship rotating around the screen. but i have the following 2 problems with firing the players bullets:
1--how do i get the bullets to fire from whatever angel the player is at, and then travel toward the center of the screen? can you post an example capx?
2--also, i'm trying to provide both touch and keyboard support...how do i get the key down function to fire bullets continuously (i.e, as long as the space bar is pressed to fire bullets at a set speed and stop firing bullets only when the space bar is released)?

thank you for all your help

Were you able to finish the game? I'm just starting on it. I loved this game in the 80's :)

@Justin1967,

I made a low average version for a C2 game jam a while ago. You can muddle your way through it here if you wish!

Hey Colludium,

Awesome! Great graphics.

Can you explain how you made the cool attack waves?

By using a lot of variables with a lot of maths, blended with some trial and error. Scale was determined by distance from the centre and each wave had a hidden rotating object that acted as an angle reference.

colludium
your game was really good, and the formation was a very good new innovation to the classic game. i loved it.

to answer your original question, i got half way with the game and put it aside for a while and went back to finish another game i'm working on...it should be done by the end of this month...its a remake of a 80s game, i hope you can play it and find it as fun as i have. i'll post more in a couple of weeks.

Thanks @hyem, I really appreciate it! I look back at it now and think that there are so many things I would do differently - I might make another version one day....
