Validation checks.

I did some coding today on the prefab builder. I want to get most of the possible functions in before I go and build a load of test prefabs. If not I'll have to go back and rebuild them, or build a bunch of new ones.

Since I'm hoping that later people will help to expand the game by making new prefabs I want to make sure the prefabs are valid before saving them.

This one is not valid. Need to add a message to state that fact eventually...

Right now I've only included a couple of checks, there are more I should add. Such things as checking if a prefab has any encounter areas set, if it has a valid walkable path from the entry hook to the exit hook (pretty essential to avoid game breaking prefabs), if it has any invalid door or stair placements and other things like that.

The check for stairs came to me when I was thinking of how to deal with stair containing prefabs vs non-stair containing ones. How can I choose the right kind in the right situation? Why should there be two types? Why not include stairs in every prefab? Then when placing the prefabs the algorithm can decide if the stairs are needed or not. If they are not needed then they can be replaced by plain floor tiles. If they are needed the level builder can decide if they should be stairs up or down.

This way makes it much easier to lay out levels and have down stairs match co-ordinates with the upstairs while still having stairs placed in logical locations, and having things such as door guard encounters and safe rest areas at the bottom of a new set of stairs.

Automating Level imports from Blender to Godot

Recently I've been making some levels in Blender an importing them into Godot. There are only about 7 or 8 shaders for each level, not counting dynamic objects which will be added later. But to improve rendering performance, it can be a good idea to split the meshes up into sections. At that point you might be faced with a list like this: Or it might be even more chaotic, if you didn't use simple names for the objects in your level. So it can take a long time to sort out all the meshes, make them unique and add textures and so on. Blender imports with simple Blender textures, or with placeholder materials. This is sometimes OK, but if your Godot shaders are very different to those used by Blender, it means applying new materials to every mesh object in the level when you import the scene. I found that during the design process, I was importing and readying a level several times before I was happy with the final layout. So at first I was wasting a lot of time. In Blender, I us

Upstairs / Downstairs.

I've decided to make my prefabs multilevel. Later this should allow me to add pit traps and other great stuff. It also makes it easier to line up stairs so that you can exit them on the same co-ordinates where you entered them. The prefab editor is pretty much finished, it just needs some code for loading up prefabs from a saved dictionary, so that they can be checked or edited. The entries will need to be forwards compatible, so I'll be loading each tile and then translating the indexes to a new array, that way if I add extra indexes or extra info (like traps or puzzles) I'll be able to update existing prefabs to work with the new standard.

Make your game models POP with fake rim lighting.

I was watching one of my son's cartoons today and I noticed they models were using serious amounts of simulated rim lighting . Even though it wasn't a dark scene where you'd usually see such an effect, the result was actually quite effective. The white edge highlighting and ambient occluded creases give a kind of high contrast that is similar to, but different from traditional comic book ink work. I'll be honest, I don't know if there's a specific term for this effect in 3d design, since my major at university was in traditional art. I learned it as part of photography. You can find plenty of tutorials on "what is rim lighting" for photography. It basically means putting your main sources of light behind your subject so that they are lit around the edges. It can produce very arresting photographs, either with an obvious effect when used on a dark subject ... ..,or as part of a fully lit scene to add some subtle highlights. See ho
