Now, QuickDraw sprites don’t have a castmember assigned as they are dealt with in the channel (That’s how I perceived it). This one had a very easy fix, but I went looking for the cause in a completely different direction, checking potential resources we might not be loading, why the shapes didn’t have a CastMember assigned (as they were QuickDraw sprites, duh) Next, QuickDraw shapes were not showing up in D4 apartment movies. So the code that solved this issue was djsrv’s. Turned out that code worked (it basically rectified our event handling).
He sent a patch to be applied and see if it works. You can check them out at /scummvm/director-tests and load them in Director 3.1 and Director 4 to play around.ĭjsrv had also done some digging with the message hierarchy, and he seemed to quickly understand what was wrong. Explaining theme here would be a lot (these blogs are meant to be a quick summary of what I was up to), but I made 2 test movies as sev said it would be important in understanding exactly how things work and what is wrong with our implementation. Turns out, there were some quirks of both D3 and D4 about handling these messages.

Now there are these 4 scripts that can act on an event -> movie script (Applied to the whole movie), frame script (a score script applied to a whole frame), sprite script (a score script applied to a certain cell to a sprite) and the castmember script (script attached to a castmember). Specific events are passed to the various scripts in a specific order. Here is an image to help understand what was happening: This turned out to be a pretty interesting issue.
while D2 movies worked fine, D3 and D4 apartment movies, (particularly the Pattern Viewer movie) would navigate to the help screen on pressing the next button, even when they were not supposed to.

sev asked me to look into this, as this would give me a better idea of how to tackle issues for other targets (like Meet Mediaband). Now we have barebones support for multiple casts (barebones = just an array a hashmap of casts with the first one being the loadedCast). But starting from D5, the concept of shared cast became obsolete, and a movie can have more than 1 cast. Till D4, we have a single cast for each movie, and a shared cast for all the movies in the project. sev told me that this is something wrong. I had been indiscriminately using it, and there were some places where it was already there (although fewer instances than what I had introduced). Don’t worry, I am listing what I did and what the week was like.įirst thing I did this week – Remove all instances of _loadedCast outside of the Cast namespace.
