Quick Key Repeat

[hotdog1234]

I've seen in a lot of ASM games that when a key is held down, actions repeat instantly until the key is released. But in most functions of the calculator, including TI-Basic key, if you hold a key down, there's a delay before repeated actions. For example, in a menu, if you hold the down key, the menu selector will go down one line, then if you keep holding the down key, there's a delay before the menu selector scrolls smoothly down the menu.

How do you turn on Quick Key Repeats in an ASM program?

Pretty much, you directly read the key port with the in/out instructions. The process is a little trickier than a typical GetKey command because you also have to mask out unneccesary keys manually and control your own timing. As far as altering the key timing outside the prog, maybe that could be done with keyhooks.

Ah, okay, it proves that the TI-83+ Flash Debugger is not a good emulator. I used the in/out ports and had to test the app on my calculator to see that it indeed worked.

On the other hand, you have to make sure that when somebody is selecting something in a menu, that when you press down an arrow, it does not scroll too quickly between the options, or else it is hard to select them.

Yeah, it's really difficult to find the perfect balance between moving once if you tap a key, yet also repeating instantly if you hold it down. I was eventually able to get that to work by putting a key check in my interrupt handler.

One thing you could do in menus is just number the options. Or use _GetCSC as opposed to direct input for the menus.

Oh man, dont use the Flash Debugger, it only emulates the most basic of calc features, and even then only loosely. Use PTI or Wabbit.

... or TilEm. (which doesn't emulate certain of my roms, but when they work, they work as they should)
