Switching directions for bullets

[AnimeTank]

My game is coming along great. One bug i have is the direction the bullets are going. You see, my character has a gun but when i shoot, the bullets go one direction. Even if i'm facing the other way. Can anyone help me out here please?

okay,
make a variable called DIR.
for the draw actor event of the player,

Code: Select all

char*key=GetKeyState();
if(key[KEY_LEFT] == 1)DIR = 0;
if(key[KEY_RIGHT] == 1)DIR = 1;


and for the create actor event for the bullet,

Code: Select all

if(DIR == 0)xvelocity = - 10;
if(DIR == 1)xvelocity = 10;


if you still need help let me know.

I wrote all the information you gave me in the script and it worked out fine, but theres another bug. It's kind of difficult for me to say but let me try anyway. When i shoot my gun one way and then i turn the other way, the bullets then change direction and head the way i am looking! If i shoot and turn the other way, the bullet is just gonna keep going the direction i'm facing... back and forth, back and forth. Can you help me out?

on create actor event use the velocity calculation,
not on the draw actor event.

[AnimeTank]

??? Can you specify?

??? Can you specify?

your code may look somthing like this on the draw actor event of your bullet,

Code: Select all

if(DIR == 0)x -= 10;
if(DIR == 1)x += 10;


do not use it like that,
use it on the create actor event,
only change x to xvelocity,

Code: Select all

if(DIR == 0)xvelocity = -10;
if(DIR == 1)xvelocity = 10;


got it?

[AnimeTank]

Hmm... i don't know whats the problem. I tried everything you told me but it still does what it usually does... Hmmm, i wonder if i'm doing something wrong...

Send me the file. (.ged and data)

[AnimeTank]

It won't let me. It says that the extension ged is not allowed?

[Oman]

you have to put it in a zip file, dont you?

Post your bullet actors scripts here. I want to see it's create actor script, and it's daw actor script. This information will help us fix your problem.

[AnimeTank]

It's exactly like the way sparky posted them, because i copied it then pasted it onto my scripts

Code: Select all

if(DIR == 0){x -= 10;}
if(DIR == 1){x += 10;}


Code: Select all

if(DIR == 0){xvelocity = -10;}
if(DIR == 1){xvelocity = 10;}


Corrected...

... Use Two Bullets One Going One Way The Other Going The Other ...

[Sgt. Sparky]

Code: Select all

if(DIR == 0){x -= 10;}
if(DIR == 1){x += 10;}


Code: Select all

if(DIR == 0){xvelocity = -10;}
if(DIR == 1){xvelocity = 10;}


Corrected...

you do not need the { and }
but
all you must use is the create actor event of:

Code: Select all

if(DIR == 0)xvelocity = - 10;
if(DIR == 1)xvelocity = 10;

if you used a draw actor event you would still have the same problem.
(it would change the direction of the bullet all the time)
on the create actor event it only changes it once.

sorry for the confusion.
