hi every one
i m trying to make a simple AI for an ennemi
it has to move a certain distance to the right/left (hspeed =+-4),
than stops (hspeed = 0);
choose to go right or left a certain distance, stops etc.

when it stops (hspeed = 0) an alarm is triggered to choose left/right and calculate the distance to go;

the problem is: the alarm event is not triggered when hspeed = 0;
so my hspeed stays equal to 0.
and my variable" a" does not change from the one calculated in the "create event"


here is the code

event create

facing = 1;//facing right
a = x+random(room_width-x); //random distance to move to the right

event step

if facing == 1 //moving right
{
if(x<a) hspeed = +4;
else {hspeed = 0;alarm[10]=30;}
}
else
if facing == -1 //moving left
{
if(x>a) hspeed = -4;
else {hspeed = 0;alarm[10]=30;}
}

alarm10 event

facing = choose(+1,-1);
switch facing
{
case +1 : a = x + random(room_width-x); //move right
case -1 : a = x - random(x); //move left
}

i don't understand where the problem lies thks for helping me

? I don't know if these are your problems but... Wouldn't hspeed be set like 'hspeed += 4' not 'hspeed = +4'?

no
the problems is with this alarm that doesn't work

[willowvayle]

Go to debug mode and check to see if hspeed ever equals 0

[mihashi]

when x > a hspeed = 0 but the alarm event is not triggered

that's the problem the alarm event

Looks to me like the alarm IS being set.

EVERY STEP

Change your conditional so that doesn't happen.

[johnkapid]

Make a check on alarm since it's being called on every step.
Simple solution.

Instead of using:

alarm[10]=30;

Use

if (alarm[10] == -1) alarm[10]=30;

[mihashi]

thks very much for the hint, iy worked verywell.

[mihashi]

how can i get this topic to be "solved"
