Guard Patrol

[rocko775]

I haven't seen anything on the forums or tutorials so I thought I'd ask. If there info is can you link me to it? Is there any way to get a character to "patrol" back and forth from points A and B? I got it so when load the screen the character goes to another spot, but I'm not sure how you get him to go back to the original spot and go on a loop back and forth so he doesn't do it once? Thanks.


function room_AfterFadeIn()
{
cguard.Walk(26, 185);

}

This is good so far. You should add something like this in the room's repeatedly execute:

Code: ags

if(cguard.x==25)cguard.AddWalkToPoint(100, 185);
else if(cguard.x==99)cguard.AddWalkToPoint(26,185);

Well I can see how that would work but now It gives me this error message. And after I posted that message I figured out that I could use use "Add way point" to get my character to go to another spot.  Would this cause trouble or having my guy walk and do this repeatedly execute function conflict?

Error:
Failed to save room room1.crm; details below
room1.asc(14): Error (line 14): '.AddWalkToPoint' is not a public member of 'Character'. Are you sure you spelt it correctly (remember, capital letters are important)?

Code: ags

function room_AfterFadeIn()
{

cguard.Walk(26, 185);
cguard.AddWaypoint(220, 140);


}
function repeatedly_execute() 
{
if(cguard.x==25)cguard.AddWalkToPoint(100, 185); //line 14
else if(cguard.x==99)cguard.AddWalkToPoint(26,185);
{

Thanks

Ohright, uhm, yeah, that's pretty ridiculous, sorry 
You already did it right, it has to be AddWaypoint().

[rocko775]

Well it should work but now all he does is have a walking movement, but he doesn't go anywhere. It works if I do function room_AfterFadeIn(), but not function room_RepExec(). And if I do afterFadeIn he only does it once,

Code: ags

function room_RepExec()
{
cguard.Walk(26, 185);
cguard.AddWaypoint(220, 140);
}

I have version AGS 3.1.2 SP1 would this cause any trouble?

It's because you're calling Character.Walk from RepExec() without any conditionals (so he restarts walking every frame).

Try this:

Code: ags

function room_RepExec() {
  if (cGuard.Moving == false) {
    if (cGuard.x > 200) cGuard.Walk(26, 185);
    else cGuard.Walk(220, 140);
    }
 }

Sweet! It worked. Thanks.

I'm just wondering can you get him to do more spots than two, like a square or is really complex? I'm not going to do it, I just would like to know if it's possible.

Yes, you can do it with the help of the wonderful Character Control Module which makes these kind of tasks simpler.

...can you get him to do more spots than two, like a square...?

Anything is possible

Code: ags

function room_RepExec()
{
  if(!cGuard.Moving)
  {
    if((cGuard.x == 100) && (cGuard.y == 100)) cGuard.Walk(100, 400);
    if((cGuard.x == 100) && (cGuard.y == 400)) cGuard.Walk(400, 400);
    if((cGuard.x == 400) && (cGuard.y == 400)) cGuard.Walk(400, 100);
    if((cGuard.x == 400) && (cGuard.y == 100)) cGuard.Walk(100, 100);
  }
}

a brief little code snippet on your guard walking in a counter-clockwise rotation in a square with 300-pixel sides

Btw, you don't need the inner brackets.

Code: ags

    if(cGuard.x == 100 && cGuard.y == 100) cGuard.Walk(100, 400);

I find it a bit easier to deal with when things are (encompassed) in [brackets] I guess it's programmer's choice
