Hi Philip,
Thanks so much. I can take this example and port it to a 2D scenario
using vectors and the like. This is exactly what I've been looking for.
Thank you.

Hi Gavin,
Assuming that you don't intend to let the user move in two dimensions
(e.g. your map is only a 1d grid with left/right movement), you can
implement jumping in a hacky way with a flag and a timer. BGT:ish
pseudocode follows:
const int jump_limit_ms=200; // The amount of time the character must
wait after landing before they can jump again.
const int jump_time_ms=800; // How long the character should stay in
the air.
timer jumptimer;
bool jumping=false;;
if(key_pressed(KEY_J) and jumping==false and
jumptimer.elapsed>=jump_limit_ms)
{
play jump sound;
jumping=true;
jumptimer.restart();
}
if(jumping and jumptimer.elapsed>=jump_time_ms)
{
play landing sound;
jumping=false;
jumptimer.restart();
}
Of course, you'll want to wrap this into a more modular player class.
This is just a very basic starting point from which you can build
further. Remember that with this setup it is perfectly fine for the
player to move in the air; you just have to check the jumping flag to
see if anything special should happen if the player moves onto a
particular tile while jumping.
Note that if you do want your character to be able to travel in 2 or 3
dimensions (e.g. proper movement), the procedure is more involved. You
will then need to move the character on the x and y and possibly z
axis depending on how high and how far they jump.
Good luck!
Kind regards,
Philip Bennefall

Thanks for the code snippet, John. The problem is that wait pauses
execution of the entire script, so while I'm in the air, I wouldn't
be able to move, shoot, or anything else.

Note that in the below, wait means execute your timer.
if(key_pressed(KEY_J))
{
height=1;//in the air
play(jump);
wait(700);
height=0;//on the ground
play(land);
}
And now whenever it matters if the player is jumped, just check the
height
variable.

Hi John,
Yes, I want to put the character back on the ground after the 700
milliseconds, but I don't know how to make that bit of code wait until
the jump timer is finished without using a second while loop, which
will
break execution of the rest of my script.

Subject: [Audyssey] Making a Character Jump In BGT
Hi all,
I'm trying to make a character jump in BGT. I managed to make it
stay in
the air for the specified amount of time, but I can't figure out
how to
make it land after that time has elapsed. I'll paste a code fragment
below:
if (key_pressed (KEY_J))
{
if (Jumper.elapsed >= 700)
{
Jumper.restart ();
JumpSound.play ();
}
LandSound.play ();
}
I have a suspicion that I'm missing something stupidly logical to make
it work. Any feedback is appreciated.
Regards,
Gavin
