Awesome, thanks for fixing it as soon as you did!

I have a question regarding the Open World project. I edited the "wmhm_overworld.png" image in Paint.net. In-game in the Stage Editor, I made sure to type in "overworld" as the world map name. BUT it's still procedurally generating the same exact terrain when I click on the "W.Map cell" button. I also made sure to click on the "rebuild world map chunk map" reset button on the main title screen, but the terrain being generated is the same.

Is there something else I need to do in order for the random terrain to change/be different besides editing the heightmap image?

The World Map Chunk Map is the data that keeps track of the coordinates where level files should be loaded (or in other words, it places the handmade map chunks on the world map), the geometry is stored in a different folder called the world cache. It's found in AppData --> Local --> (name of the project) --> cache_world. Delete every file inside this folder and it should be regenerated next time you run the game.

Comparing the two project versions, I noticed that some shapes were removed in the stage editor for the OpenWorld Edition like moving platforms, X/Y/Z tunnel objects, and X and Y cylinders. If I want to have these, do I need to add them back into the newer version?

(Also is it possible to rotate shapes along the Z axis at all, or are the "ROT" buttons just for rotating stuff along the X,Y?)

I had a look in the codebase and yeah, the code has been completely removed so they're completely gone, they're not just disabled.

The reasoning for removing stuff I remember at least, I never was happy with how the code basically needed a completely separate copy of the behavior for each axis (applying to both rendering and collision). Rotating cylinder objects in a prefab/copypaste didn't work as expected either (since they would have a rotated size but still be cylindric along the original axis) and starting to need special behavior for rotating certain objects felt like such a kludge I just couldn't keep going anymore. And the collision code for tunnels especially always was a nightmare, they are paper-thin so for smaller tunnels it was easy to get stuck, and there was no good way to connect tunnels to a start point or a corner that LOOKED right (for making sewers etc) so I always felt like they were a total failure. For making tunnel areas I'd recommend using separate prisms for the floor and ceiling instead, they even can be cobbled together into smooth rounded corners.

There's no way to rotate things around other axes. A lot of stuff treats the vertical axis in a special way (since Game Maker doesn't have a Z axis natively) so a lot of code (especially the collision code) wouldn't know what to do with e.g. a prism protruding along the X axis instead of at the top.

Thanks for the clarification. I'm definitely going to try to add some of those features back (like the moving platforms) since I'm going to be using this engine for my 3D platformer game! Also in regards to the terrain generation— using a customizable .PNG image is nice, but it would be neat if there was also an option to generate randomized terrain on the fly. You just give it the max Z height and select what biomes you want on a pop-up menu and it spits out some terrain. Just a suggestion!

Uh oh. I've encountered two more runtime errors in the Legacy version's stage editor. You might need to update it again...

This first one happens when clicking on the "Enemies" tab in the editor (I'm pretty sure this error is the same one as before, with the minus signs preceding scripts so it's an easy fix)

And then this second crash happens when placing a "Waterfall" object under the "Misc Props" tab in the editor:

I'll get to it right away!

The fix should be available now :)

In the Open World version's Stage Editor, I noticed that if you save a level with a footpath, and then import that same level with Prefab, the footpath isn't being spawned again into the correct place. Its position keeps randomly being moved along the Y/Z axis. Is there any way this can be fixed?

Yal66 days ago (1 edit) (+1)

I did some test with both prefabs and copypastes, and it works for me (including rotations, and copying a footpath + moving along an axis causing the copy to be parallel to the original), but I did notice a bug - if you don't press "enter" to finalize the path data before saving a prefab file it gets saved in an incomplete state. This might be what's happening here?

The only other things I can think of is if the origin coordinate calculation gets messed up when you load the prefab with the marker size larger than 1x1x1 or if there was some funky interaction with you having something in the copypaste buffer already when loading a prefab - does it behave as expected if you press "alt" to quick-reset the cursor before loading the prefab?

Keri65 days ago (2 edits)

Yes I did make sure to finalize the path data before saving the prefab (otherwise the path objects don't get exported at all!)

When I press "alt" to reset the cursor, that doesn't do anything because when the prefab is loaded the cursor automatically gets rescaled to the size of the prefab. So somewhere in the prefab code the origin coordinate calculation for footpath objects is messed up. Copy/pastes seem to be working fine though, so I'm not sure what's causing this
