Adjusting a jump script

[dutchy 0]

Hello all,

 

Below is a code for a jumping script.

 

It works great however I just want to be able to change one little thing...

 

If a player can Jump the distance (In my example 6 tiles) but can do it 4 or 3 because that's where the closes landing point is, then I'd like my character to be able to do that, instead of jumping the full 6 squares.

 

I've looked though a number of Jumping Scripts and did a pretty wide google search and found nothing...

 

Any support would mean the world to me

Put this script above main (and include the script you posted too)

 

class Game_Map
alias old_fucking_update update
def update
old_fucking_update
$game_player.jump_count = 0 if Input.trigger?(Input::A)
end
end

 

Now, the player will stop every time the A trigger is pressed. Don't know what triggers are? Press f1 while playtesting and you will see.

Not sure why you posted that

[Marked 197]

Valdred, that isn't related to his request. And don't name your aliases silly things.

[CrimsonInferno 35]

Isn't this what you have to change? I haven't tested it, put it looks like it. :sweatdrop:

module Nathmatt_Config

Jump_Distance = 2

Jump_Animation = false

Off_Switch_id = 50

Jump_Key = 'Space'

# Terrain_Tags

Cant_Jump = 1

[dutchy 0]

No, sorry. I'll try and explain it like this...

 

Say if a player needs to jump 4 Tiles

and the Jump_Distance = 8

Instead of jumping all 8 Tiles

He should only Jump 4 because that's where the closest land place is.

[Marked 197]

I don't think its as complicated as it sounds. In RGSS its pretty simple to get your players X and Y coordinates and his direction, so all you have to do is check the passiblity of each of the 8 squares in front of him on all 3 layers and if there is an event there. Pretty pointless to say because I can't exactly do it :sweatdrop:

Correct...

 

I just want the character to jump to the closest option. In example...

 

---Example 1----

(start) x x x o o x o o (max jump length*) *8 tiles

 

*x = can't pass *o = passable ground. (*each represent a tile)

 

If the Example 1 The player is jumping to the right, because the 4th tile is available to land on then it should land there instead of the 8th tile because that's the max jump length.

 

The only time a player should jump 8 tiles is when a situation like this comes up as shown in Example 2.

---Example 2----

(start) x x x x x x x o (finish)

 

If also possible can it be defined within that code that the minimum jump length is 2 tiles? So that the character isn't jumping one tile at a time?

I'm pretty sure thats easy. You work it out based on your characters coordinates and direction. Say if he's facing left, we're talking X, and say he's at X=4, Y=6. You got that variable already in the script, its pretty easy to do. So then to get the coordinates of the tiles we want to check for passibilty, well, you could do

$i=[variable for players X or Y c] + 2
for($i < [variable for players X or Y c] + 2 + 8 ){
  code to check passibilty, using $i as the X/Y coordinate, and the other constant coordinate
  if($i is passable){
     break and return $i
  }
  $i++
}

Actually that is kinda php but that's all I know :sweatdrop: but all of that is more or less the same in RGSS, above would be same. In fact I could probably write it if I knew how to return whether a tile is passable based on its coordinates.

Thanks for the support, I'm trying to get my hed around it all my self... sometimes i get lucky sometimes i can't get anything right... :(

[Marked 197]

Good news :) I have successfully edited this and it works :)

 

But first, do you know what terrain tags are? They are defined in the tileset tab in the database and are what makes the whole system work. Basically, you set any tile you dont want to be jumped to a terrain tag of 1(or another number, its defined in the script).

 

Here's the script.

When testing I set the jump distance to 4 and the minimum jump distance (a variable I added) to 2. So, say you're standing in front of a building (which has its tiles set to a terrain tag of 1) and you're standing 3 squares away from it, he will jump right to the wall. It would look way cooler if the min jump was set to 1.

 

Hope this is what you wanted, just reply if you have any problems with it.

I feel that I have to justify myself. My post was totally related to his request. I might have misunderstood what he was asking for, but a script that makes the player end the jump anytime by pressing a key is at least not so unrelated that it is worthy of a "not sure why you posted that." Did I explain in a bad way what it does? I'm so sorry, I'm not a native english speaker. Didn't the script work? It happens that the scriptlets I write aren't properly read trough, if that's the case it is my fault. Concerning the swearing in my code: I did not know that it was a rule against swearing, but if it is I should have read trough the rules more properly (I should have anyway). old_update is a very common alias name so to improve compatibility I added the F word (it was the first thing that came into my mind).

[Marked 197]

Ah ok, I apologize for saying it was unrelated, I understand what it does now. I originally couldn't find the connection. I didn't know you weren't a native English speaker, so your English is perfectly fine. As for swearing, its not expressly mentioned in the rules, but its more about posting etiquette. You could argue all day about whether it should be against the rules or not, I think it should be in allowed in the debate and mature discussion forum, but I don't think its necessary inside of code lol. If you want to discuss it further PM me.

[Valdred 1]

Happy ending then. No need to discuss that further :)
