RPG MAKER MV INPASSABLE TILES PASSABLE

[Antonio]

It seems my first question didn't submit or at least I don't see it, so im creating 2nd question.


I've attached 2 screenshots.


1st showing that brick wall is marked as non passable and 2nd showing that Misha is on the wall.



Why is that possible? Shouldn't the X mean that it's not possible to walk on it?

 

[Andar]

that means that you either made a mistake on mapping or on tileset construction.


Passability is determined by the passability of the (multiple) tiles on a position based on priority and on special functions.


If you place an invisible and passable B/E-tile on the same place as your wall, that wall will become passable because the upper layers have the higher priority.


Additionally, it might be that you mixed up your A4-tiles - you didn't mark the tile you used, and your screenshot shows two tiles that might have been used - a wall (bottom row) and a ceiling (row above wall) tile on A4. If you used the ceiling tile - those have a special automated passability to allow for simulating a 2-level-dungeon. That is also the reason why ceiling and wall tiles have different formats on the A4-tilesheets.


Last possibility - if you have an old version of the editor, it might be that you set your first B tile to something other than star - that is why the first B tile was fixed to star passability in the 1.2 update. Because if the first B tile is set to passable, everything without upper tiles becomes passable.

Thank you Andar for your reply...However it's strange, I generally understand English well but didn't understand neither of your points.. What are you saying?

If you place an invisible and passable B/E-tile on the same place as your wall, that wall will become passable because the upper layers have the higher priority

What you mean by this sentence?  I put impassable grass and on top of that impassable grass I put impassable brick. If top layer takes higher priority, and top layer being impassable brick what does it matter whats under it?

Additionally, it might be that you mixed up your A4-tiles - you didn't mark the tile you used, and your screenshot shows two tiles that might have been used - a wall (bottom row) and a ceiling (row above wall) tile on A4. If you used the ceiling tile - those have a special automated passability to allow for simulating a 2-level-dungeon. That is also the reason why ceiling and wall tiles have different formats on the A4-tilesheets.

yes, sorry I didn't mark the tile I used. It was the lighter looking brick wall which is just above darker looking brick wall. Either way both are having the X symbol, so both must be same...Well re-reading your sentence over and over again I grasp the gist that above lighter looking brick walls are special, however how a new user would know that? If they are X I would expect them to be X. I might not have 2 story dungeons made of brick walls, however I do have houses made of bricks....

That is also the reason why ceiling and wall tiles have different formats on the A4-tilesheets.

Sorry what special format? One looks dirty and other looks clean...Is that the special format?

Last possibility - if you have an old version of the editor, it might be that you set your first B tile to something other than star - that is why the first B tile was fixed to star passability in the 1.2 update. Because if the first B tile is set to passable, everything without upper tiles becomes passable.

First B tile is set as star even though I don't know what stars mean...What do the stars mean?


Just going on a wild here but if stars mean that tiles are special perhaps clean brick wall bricks should have been marked as stars to indicate that they are special...


Please advise and thank you for your time!

I'm not Andar, but I'll try to answer your questions


RPG Maker MV uses three automatic layers for maps. Tiles from the A tab go on the lowest layer, tiles from the B-E tabs go on the two upper layers. The passability setting on the highest layer takes priority over the other layers. Pasability can be set to X (not passable), O (passable) and Star. Star passability is "special" in a sense; it means the tile has no inherent passability setting and basically tells the engine "no passability specified for this tile; look on the layer below for the passability".


That is why it's important that the empty tile in the top left corner of the B tab is always set to Star: All maps "without" upper layers actually have this tile on their upper layer. If its passability was set to, for example, O (passable), that setting would take priority because it's on the highest layer and therefore make large parts of your map passable.


I think, however, the problem with your map is what Andar mentioned about the A4 tiles. I agree that it's not well documented - I found out about this only recently myself, and a quick look though the Help file didn't bring anything up. The A4 tiles are made for 2-level-dungeons and always come in pairs - the tile on top (the ligher one) is the top of the dungeon "wall", the tile below that (the darker one) is the side of the wall. Although both are set to X passability in the tileset setting, only the lower one is actually impassable. The upper one can be entered from below. (I can show you an example map if you would like to see how that can be used in dungeon design; the main point is that the "light" A4 tiles, like the one you used for the house, are supposed to be passable under certain circumstances.)


So, to fix your mapping problem, there are at least two possibilities: Either you switch to a different tile for your brick wall (e.g. the darker bricks or one of the tiles below the roof tiles) or you edit your tileset graphic in such a way that the lighter brick graphic replaces an actual "wall" tile.


I hope that helps you unterstand a little bit better. If anything is still unclear to you, just ask

That is not a lighter looking brick wall, that is the brick ceiling, and yes that IS passable, just not in the normal passability.


If you look not at the tileset but at the tilesheet, you'll see that the lower (wall) autotiles are 96x96 pixel in size, but the upper (ceiling) autotiles are 96x144 pixel. You can't see that iin the tileset, only in the tilesheet picture, because all autotiles are using a regular 48x48 placeholder in the tileset.


The different functions of the tileset and tilesheets are explained in the help file and several tutorials - I suggest you follow the link "starting point for new users" in my signature and work through those tutorials - if you don't know those differences, you probably never heard of shift-click-mapping either, and you can't make good looking maps without that option.

Thank you both!
