Norman Sword Posted March 24, 2021 Report Share Posted March 24, 2021 (edited) I also included a full screen Second title page. Which is displayed after the boot. This is what the current 2nd Title picture looks like. Edited March 24, 2021 by Norman Sword Addition of a picture.

Norman Sword Posted March 24, 2021 Report Share Posted March 24, 2021 (edited) Cutting it fine. When I first watched the jumping across the skylab landing bay. I was convinced it was pixel colliding and I had to check my code. I took a series of still frames to see how close Willy was to a pixel collision. Willy lands amongst the debris of the skylab. The pixels merge. Edited March 24, 2021 by Norman Sword bigger image size - the original was too small IRF, jetsetdanny and MtM 2 1 Quote Link to comment Share on other sites More sharing options...
jetsetdanny Posted March 25, 2021 Report Share Posted March 25, 2021 Very nice, Norman Sword! 👍 I will create a separate page for the 'Creme de la creme' variant of MM on this list, when I continue updating JSW Central, which has a high priority for me.

IRF Posted March 25, 2021 Report Share Posted March 25, 2021 (edited) Interesting animation, Norman! Willy's legs seem to be surrounded by several pixels of debris/dust just before he lands, but without ever actually being touched by any of the dust pixels - a close escape indeed! (Incidentally, Norman's animation misses out a frame of the Skylab crumbling - but it's early on in the process when Willy hasn't quite reached it yet, so it isn't germane to studying whether or not he pixel-collides with it.) *** This has actually reminded me of something that I meant to ask Crem - when you get a moment please, would you be able to get your algorithm to replay the two caverns in the Software Projects version of Manic Miner which have different guardian sprites (namely The Warehouse and Amoebatrons' Revenge)? Because it's possible that the difference in sprite forms might mean that Willy can achieve a higher score in those caverns - especially in Amoebatrons' Revenge, where the vertical guardians don't have all those dangly tentacles, so it might be possible to eliminate some of the 'waiting around' that Willy has to do in the Bug-Byte version of that cavern! (Incidentally, the SP version of Processing Plant also has different graphics for some of the Fire cells [and item shapes], but those shouldn't have any impact on the maximum possible score since the collisions with Fire cells are attribute-based rather than pixel-based.)

Surely will do! Could you help me to pick a right file with this version, is it this one? (from worldofspectrum) Do you know if the memory layout is the same in this version?

Norman Sword Posted March 25, 2021 Report Share Posted March 25, 2021 The missing animation frame. I used an online Gif animator to create the animation. When I watched the animations the first time, it was noticeable the frames were out of order. The file numbers are consecutive, but on uploading they were re ordered. The thumbnail sized pictures made it very difficult to rearrange the order of the pictures. After going through the process several times. Due to being unhappy with the output. And duplicating the process of ordering cropping, enlarging, changing frame rates etc. I decided to just delete the one obvious out of order picture and carry on.

Not a problem, as I said it's early on so not relevant to the studying of pixel-proximity. But I was looking at the individual frames of the Skylab's disintegration, and I could only count seven [including the descending version before it starts to collapse], whereas there should be eight. But then I noticed that Willy advances through his jump by two frames at one point (as I said, before he reaches the Skylab), so I realised that one frame must have been skipped (for whatever reason, which you have now explained).

That's only the case with guardians (including Eugene, Skylabs and Kong*). Room cell interactions (including Fire cells), item-collection, flashing portal entry and the air-supply sapping effect of the solar beam are all based on Willy's attribute coordinates. (*In the case of Kong, a pixel-collision with Willy is only fatal whilst he's on his perch, not when Kong is falling.) *** Incidentally, in Jet Set Willy, collision with arrows is based on both pixels AND attributes (hence Willy can hide behind Water cells, where his INK isn't white, and arrows will apparently pass straight through him without killing him!) And another JSW oddity - ropes pick up Willy based on a pixel collision with ANY infilled pixel (not just part of Willy's sprite), which can cause him to suddenly jump up onto the rope from the other side of the room, if the rope passes through a room block with infilled pixels! crem and jetsetdanny 2 Quote Link to comment Share on other sites More sharing options...
IRF Posted March 25, 2021 Report Share Posted March 25, 2021 (edited) Another little-known fact about JSW - Willy can be detected as having reached the toilet during the toilet-run if he is eight character-rows above the toilet, in the upper half of the room. (If you extend the ramp in The Bathroom down to meet the floor, and put a hole in the upper platform above the toilet, then start the toilet-run, watch as he runs up the ramp, drops down the hole, and then disappears mid-descent rather than falling all the way into the toilet!) But I've gone way off topic now! 😁 Edited March 25, 2021 by IRF andrewbroad and jetsetdanny 2 Quote Link to comment Share on other sites More sharing options...
