Quote from: Cumred_Snektron on May 18, 2015, 06:03:39 amWhats a GROB btw?It's been the HP parlance for GRaphic OBject since 1989 or so.As for the problem for which I was summoned - there are a couple of questions to ask here.Are you really meaning to create a 1600x800 <unit> sized GROB?If so, are you remembering that the <unit> size comes from the Cartesian grid of the current application? So if the function app is running and the user has zoomed in by 2x on the graph, your GROB size just doubled which would already cause your memory to run out. My recommendation would be to always use the _P options to specify an exact size else you are left at the mercy of what the user has done to the Cartesian grid. If you really want to use the cartesian grid, you'd better make certain you set the values to the desired setting by using the Xmin/Xmax/Ymin/Ymax. However, those only exists for about half of the apps that have graphing. Better to just pick your correct pixel size.Are you cleaning up after the exit of the game? By this, I'd recommend clearing out your large graphics by setting them to 0 or 1 pixel in size. Else that memory will stay in use until the user either resets, or stores something else in there.With the new firmware, I'd recommend switching to an application. That will give you access to permanent variables that aren't lost on editing, as well as files and an icon for your program. My recommendation would be:1. Save a copy of the Quad Explorer app (this will be very tiny). 2. Make your START routine be to launch the game, as well as the Plot, Symb and Num routines.3. In the code itself, get rid of all the uses of ICON. On the PC, you will see that the applications are now folders of the form "<name>.hpappdir". Put all your graphic assets into that directory as png files (.png on the name is not necessary for use/loading - we check the header to determine type) and they will be sent along with it when sending from the connkit.4. Give a 38x38pix item a name of "icon.png". That will be what is used for your application icon.5. When you want to load your png files, use G2:=AFiles("filename") or similar. I'd avoid using the AFiles(1) as that file order could change! It depends on what the underlying file system does with the files in how it lists them. Then once you have G2, you can use that to create your larger GROB. Going directly from the png decode to the blit will definitely increase load time.6. If you have data you want to save, AFiles("name"):=G1 will store it out. You might even be able to store the PNG as built to disk. Not certain of that though due to the large sizes that appear to be involved.7. If you have data you want saved (scores, map info, etc), do a AVars("name"):=<list_or_whatever>. Note that the primary difference between using AFiles or AVars is that AVars will allow you to use the object directly as a variable (tying MyVar for example) while AFiles will not. You have to load to a variable from AFiles before use. AVars will consume RAM when the app is loaded. AFiles will not until they are recalled to a variable.8. To distribute your new application, just package the "name.hpappdir" in a zip file! People just need to drop that zip on the calc in the connkit and it will send the application. No messing with pasting of source. This is the strucutre we like to use for distributing HP developed apps for teacher use for example:<ZIP> |-- appname.hpappdir | |-- stuff |-- readme.txt |--help.pdf \--last fileProvided your stuff is not an hp object type (.txt, .pdf, etc) it will not be sent. Anything in the hpappdir WILL be sent as a file, but it will not recursively add things (aka, no nesting of directories in there).
Whats a GROB btw?
