# Enemy incoming, XY distance

#### v1c10us

Hello. At first, sorry for my poor English. I'm trying to make a game in the atmosphere of Silent Hill. If you played "Silent Hill", you probably remember the radio that was warning you when the enemy was close. The noise from the radio was getting louder when enemies were nearby. I wanted to implement that in my game, but after hours of trying I just gave up. Can any1 help me make this work? I'm uploading screenshots with this post and legend to them below:

001 - Player XY coords set, Enemy (Monstrum) XY coords set, and Player XY sub Enemy XY coords.

002 - The event that changes depending on the Player and Enemy distance. Each event has it's page and is activated by Switch NOISE A (the enemy is far), NOISE B (the enemy is getting close), NOISE C (the enemy is close to player).

003-A/003-b - Here's where I totally failed... I have no idea why it's not working... According to my calculations, it should work But it's not... You can see how I calculated this on picture number 005 (Dźwięk = Sound/Noise). On picture 004 there's only empty map (not sure why the hell I uploaded it anyways...) I wonder where I did mistake? If there's any1 that can make a quick example in RPGM MV and attach it, or upload a plugin, or just simply explain how should I do this, I would be very grateful. THANKS SO MUCH!!! <3

Hey,

at first sight I can see that your if/else statements can not work the way you set them up.

If you put one if into another, it means that you check for case 1 to be true AND case 2 to be true. You have to use else instead! (Please note the small check box in the conditional branch command "Create Else Branch")

In your screenshot for example you check if variable 1 is between 6 and 3 AND between -6 and -3 which will never be the case

Using positive and negative values to determine the distance between monster and player looks extremely cumbersome to me. I would advice using some JS here: Math.abs() returns the absolute value of a number. You can use that with your variables.

Please note that I used 6 instead of 4 variables because it was easier for me to get into your problem.

In case you're wondering: Calculations like this can be done in the Script field in Control Variables.

No longer dealing with negative values, you'll have much less trouble defining the if/else statement. Mine looks like this:

I really hope this helps.

Oh, and hopefully you can bake. I claim a cookie for all that effort!

Hello there again! Sorry it took so long, was busy at work Finally I could test the method you showed me and guess what... IT WORKED!!! Gonna take me some time to totally understand it (I was never good at math...), but I will eventually get it by making my game further You are genius! Much love <3

Erm, I mean: Glad it finally worked out for you

It takes some time getting used to RPG Maker, but you'll figure it out eventually. When you need further help, you can come back here anytime!

• Now I have another problem... When my enemy is on the edge of right side on the map and I'm on the left edge, the event "thinks", that he's close to me somehow... Is there a plugin or a solution to solve it?

EDIT!!! Never mind, I did something terribly wrong

Time for the next chance for y'all to affect my advent calendar! Where should Day 7's sprite come from: land, sea, or demon realm?
Throné's final boss is weird. He is a guy holding a baby while fighting off attackers. I think his name was Santos. I might be thinking of someone else.
I think I've just about finished fighting the fight with the tileset I was most intimidated by for game jam. No pictures yet, the map isn't presentable, but I think the tileset will work! I'm very relieved XD
Twitch! At it again with more gamedev for a couple hours, followed by some Valheim with my friend. Feel free to drop by~
these 80+ gb updates on several years old games are the absolute worst. I just want to play for an hour or so before bed to unwind. Sorry, gotta spend that time downloading an update. Then my mods will be broken so I'll have to start over or wait for those to be updated to. Is a complete game within three years of the pay to be a beta tester period really to much to ask?
