I've made a few changes to my Alchemy word game, that make it a bit more enjoyable to play. I've also re-checked each pair of words and verified that they are solvable within the number of moves allowed, and provided my "best results" in the Pairs list in the game, but these can be reset to the maximum of 21 changes. The files are attached as a 7zip file.
The Wordlists folder needs to be in the same folder as the alchemy file.

I went on a complete tangent from what I was intending to do this evening when I stumbled upon _MAPTRIANGLE!

First this project creates the vertices of a cube - but it does this based on a hard-coded TESSELATION constant. If this is set to one then each face of the cube has four vertices, if it's set to two then each face has nine vertices, 16 vertices for a value of 4, etc.

The reason for allowing the tessellation is that the project continually morphs between a cube and a sphere (while rotating on three axes). The higher the tessellation value, the better the quality of the sphere but also the greater the number of vertices, calculations, triangles to render, etc. I wanted the code to be clear and well commented so it isn't optimised at all (which is why I've set the tessellation value quite low).

The ZIP file containing the project and its assets is attached. As always, you can also find the code over at my GitHub.

On a side note, does anyone know if _CLOCKWISE and _ANTICLOCKWISE actually do anything at the moment in _MAPTRIANGLE? I tried using it to do the back-face culling but it didn't seem to have any effect so I ended up using cross-products for the culling.

On a second side note, is there any command for altering the brightness while rendering? I had a brief go with _SETALPHA for each triangle being rendered but (a) it didn't seem to affect _MAPTRIANGLE and (b) the performance impact was horrendous.

I stumbled on _MAPTRIANGLE and thought I'd take it out for a spin. It's got me wondering whether _CLOCKWISE/_ANTICLOCKWISE are implemented?

Unless I'm reading it wrong, they should allow automatic back face culling but I'm finding that, with a test triangle, I can apply the coordinates in any order and it will render regardless of whether I add _CLOCKWISE or _ANTICLOCKWISE.

Any insights on this?

One function to set the direction of your slashes for the proper OS.  It's just that simple. 

I was under the impression that at some point QB64 had the ability added to change the backslash character in path strings to foreslashes if it detected it was running within Linux.

For example, this line of code:

MySprite& = _LOADIMAGE(".\assets\sprite.png", 32)

would be seen as

MySprite& = _LOADIMAGE("./assets/sprite.png", 32)

when running in Linux. Was or is this still the case or is my age showing again?

I really need to get another Linux box up and running so I can test these things out.

Hello,

Unfortunately, the last version 3.5.0 doesn't compile on my iMac 27 under macOS High Sierra.

I get the following error message:

What has happened there? With all browsers, Chrome, Edge, Firefox.  

Hello,

The third mouse button (scrolling the content back and forth) doesn't work at all on the IDE under macOS.
Is there a fix planned soon since this problem was already reported long time ago and that without this capability, the IDE is almost unusable on a Mac.
TIA for news about that.

Cheers.

Hello,

when loading qb64pe.bas into QB64PE 3.4.1, there is an error message in the IDE saying :

Name already in use (DECLARE) on line 3911 (click here or Ctrl+Shift+G to jump there)
caused by (or after): A$ = "Expected SUB/FUNCTION definition or END", 39 DECLARE " : GoTo errmess",13

Can anyone help me to fix that?

TIA for your help.

Cheers.

Hello,

The option "Open" (or the Ctrl O command) of the File menu of the IDE simply doesn't do anything on my iMac27 (High Sierra).

Any way to fix that since I can't use QB64PE 4.3.1 at all.

TIA for your help.

Cheers.
