hi, i wanna know how to make the player to perform an action for a certain time. for insteance, i press the key space and it walks for 3 seconds and then stops.

var counter = 48; // 16ticks * 3 = 3 seconds
while(counter > 0)
{
walk
counter -= time_step;
wait(1);
}

EDIT: nevermind...

it works fine except for one prob: it only allows me to do it once. i press space and it does what i want, but then if i press the key again it doesnt do the movement anymore

yeah that's exactly what i have but after doing the action once it just doesnt wanna do it again when i press the key again

CODE

if(key_space)
{
while(counter > 0)
{

c_move(me,vector(10*time_step, 0, 0),vector(0, 0, 0), GLIDE);
counter -= time_step;
wait(1);
}
}

That's obviously not exactly what you have otherwise it'd be workingWhere's while(me)?

while its on top of the player code but its "while(1)" ahyway i changed it by (me) but its the same. the whole its long becaus eit has a some other movements is this

var floor;
var gm_percentage;

Your code is different to MrGuest's and my advice, the mistake is obvious: You've removed "counter = 48;" from the line before the while(counter > 0) loop, i.e. you only set it once to a value (10) above zero. The next time you press key_space, counter will be of course < 0 and thus the while loop will never be executed.

Btw. it's horrible to look at this code without indentation, next time please use the [code ] my code here [/code ] tags (without the spaces between code and ]).

It's impossible to see what's going on in your code, your naming convention should have some representation of what the variables are doing

SJ, js and rt mean nothing to me and won't do to you in a couple of weeks after you close this file.

use [ code ] [ /code ] tags when you post that much code so it stays indented

remove everything you don't need and just get the basics working

and ensure you've attached the player_script to the player.

once you've done that I'll have another look
