Sight Range (Events hurt my brain :P) [Resolved]

[seven]

Okay, so I have a scene in my game where after a switch is on, several guard NPCs will move in a specified pattern, and when the player is 5 tiles away or less in the direction they're facing, witty bantering (Show Text: We caught you go die mwahahhah etc. etc.) and then it displays a gameover graphic. I think I understand most of it, but the actual sight range event system has me stumped.
Any help would be appreciated. :smile:

Hmmm...so this is like the classic guard minigames in Zelda games? (like Ocarina of time) If so, I think this might help. It allows events to see in front of them. However, I'm not sure if it's in a straight line, or a semicircle. Even if it is a semicircle, however, I think you can modify it so that it only sees in a straight line.

Hope it helps! (By the way, if you use it, credit Monsta)

If you want it done with events, try this.

You need to use a different event (parallel process) and a different variables for every guard.

@Davester: As the tag shows, this is for VX.
@Doctor: I'll take a look.
Edit: Can you please use imgzoom on that screenshot? I have to squint a bit to look at it. Thanks.

You can just quote his post to find the image link. :tongue:

I seem to have a problem.

I did everything the way he said, but the guard's got eyes in the back of his head!

For right and up, did you change it to >= -5?  It has to be greater than and negative because of the subtraction properties.

By the way, Doctor, thank you!  I was just trying to do this and I was failing.

I never bothered to set right because he only walks up and down, but yes, it is greater than or equal to with a negative. Should I post up a screenshot with the event code?

 

[Stardust]

Is it set to parallel process?  It won't work otherwise.

If that's not the problem, then yeah, you should probably post a screenshot.

In the Conditional Branch where the enemy's facing down, change the 5th line to "variable 29 -= variable 27" and then check if variable 29 <= 5 rather than variable 27.

Thanks Regi, that seems to have worked, but now when the enemy faces up he can see infinetely far..?

 

[regi]

In the Conditional Branch where the enemy's facing up, change

@>Conditional Branch: Variable 27 >= -5

to

@>Conditional Branch: Variable 27 <= 5

Also, I think you might want to nest that in another conditional branch that checks if variable 27 >= 0 (and repeat for all directions), because otherwise if you're behind the enemy he can still see you.

Argh.. I think I may need a demo.

 

[Stardust]

Ah, I found the problem!  When you just have <=, it can be negative as well, which means they can see behind themselves.  You have to add a >= 0 conditional branch in there.  Anyway, I created a quick demo.  Pull the switch to change the monster's direction.  I changed some of the variable operations so that you've always got <=2 and >=0.  I hope it helps. :thumb:

I'll try this out, thanks. Sorry for the late reply, been busy and my internet connection failed me earlier today. >_>
