16x16 movement

[second_crimson]

This is for RMXP (RGSS)

I've been racking my brain trying to find out how to do this...so far no luck.

Basically I want to change the way the player and other events move. I want them to move based on 16x16 tiles, or in other words, I want to halve the size of all map aspects. I have accomplished the graphical side of things by using Sephirothspawn's Tilemap rewrite and changing @tilemap_tile_width and @tilemap_tile_height to 16 (instead of the default 32). Like I said, this accomplishes the graphical side of things nicely. However, the map is still being treated like it is normal size. I want to make it so that all characters move 16 pixels, and the default screen is essentially 40x30 (16x16 tiles).

No, I don't want to have to go to Pixel Movement...I will if I have to, but I'd rather stick with simple tile movement, just shrink it by half.

My problem? I don't know where to start. I tried fiddling around with Game_Character's Screen_X and Screen_Y methods...but I just can't seem to get it to work. Any help would be very much appreciated.

EDIT: I may have fixed it, by switching the Tilemap rewrite to zoomout instead of chane tile width, and then going into sprite_character and halving its x and y. However I am still interested in how others would have gone about this, just in case my workaround ends up being disadvantageous.

Try to make the changes on the move methods (move_up, move_down...)

Eg.:

def move_down add "+1" to charcater @y. so try change it to "@y += 0.5"

 

[LegacyCrono]

def move_down add "+1" to charcater @y. so try change it to "@y += 0.5"

Won't work. The movement will work fine, but there will be issues with collision checking and general problems with the events.

I tried fiddling around with Game_Character's Screen_X and Screen_Y methods...

That's quite right. You'll have to adapt those methods but there's also other problems you'll find. Game_Map has some values you'll have to change to fit the 16x16 tiles, like the screen center and other things I can't remember right now.
Sorry, I can't remember the whole scripts. I don't have RPG Maker installed here, and it's been a while since I've coded RGSS for the last time.

Hope this helps. Good luck!
SEE YA!!!!!

@Atoa - Thank you for the help, but as LegacyCrono said, I don't think that would work.

@LegacyCrono - I did have to tweak the screen centering, but I think I figured it out. I'm glad I seem to have gone about it the right way. Thank you for your help.

But that works in part, the characters will walk 16px.
As you said:

I gave you a starting point.
All you would need is to fix the passability issues.

This is the move down method

  def move_down(turn_enabled = true)

    if passable?(@x, @y + 1, 2)

      @y += 1

      increase_steps

    end

    turn_lower_left if turn_enabled

  end

try this:

  def move_down(turn_enabled = true)

    if passable?(@x, @y + 0.5, 2)

      @y += 0.5

      increase_steps

    end

    turn_lower_left if turn_enabled

  end

I'm not 100% sure if that will work perfectly. but that is an good start point. If it have any issues, just fix them.
