Axe r command

[boathouse2112]

In a few programs, like this greyscale snippet:

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

[ffff0000ff00ff00]->Pic1F [ff00ffff00ff00ff]->Pic1B [ffffffff00000000]->Pic2F [ffffff00ffff0000]->Pic2B ClrDraw ClrDrawr repeat getkey(15) Pt-Off(0,0,Pic1F) Pt-Off(0,0,Pic1B)r DispGraphrr Pt-Off(0,0,Pic2F) Pt-Off(0,0,Pic2B)r DispGraphrr End

there's a command "r" following some of the parentheses. I tried looking it up in the documentation, but can't find anything on it. Any help as to what it is?

The "r" suffix (which is the radian symbol from the ANGLE menu) is typically used to denote an alternate version of a command. In the case of graphics commands, usually it means that it should be drawn to the second buffer, or "backbuffer". Grayscale uses the main buffer and the backbuffer together to create the full 4-level image.

First of all, it is the radian r.
Second, used behind something drawing thingy (like pt-off) it tells it to draw it to backup-buffer, and you need DispGraphrr instead of DispGraph for 4-level greyscale.
DispGraphrr must be called very often otherwise it won't appear as greyscale

You could also optimize that code

Spoiler for Hidden:

[ffff0000ff00ff00]->Pic1F [ff00ffff00ff00ff]->Pic1B [ffffffff00000000]->Pic2F [ffffff00ffff0000]->Pic2B ClrDraw ClrDrawr Pt-Off(0,0,Pic1F) Pt-Off(0,0,Pic1B)r Pt-Off(0,0,Pic2F) Pt-Off(0,0,Pic2B)r repeat getkey(15) DispGraphrr End

EDIT: y u ninja me calc84maniac

Thanks for the answer. The code was copypasta from a tutorial.

[Deep Thought]

If you look in Commands.html (it's got all the Axe commands documented), you'll see the commands that have a radian r suffix. It'll tell you what it does to the command.

Oh, lol
Then the tutorial isn't good

EDIT: forget my 'optimization', i didn't look at the possition of the sprites, lol
