Sorry for the unclear title but i couldn't think of something better.
I am trying to create a load from MS function but it seems to crash here:
Code: Select all
unsigned char count=0;
unsigned char cursor=0;
SceCtrlData pad;
msg.ShowMessage("testpoint -1",0);
bool go=1;
while(go)
{
GraphicsObject::endFrame();
GraphicsObject::startFrame();
pspDebugScreenSetXY(0,0);
pspDebugScreenPrintf("Files:\n");
count=0;
for(std::vector<SceIoDirent>::size_type i=0;i<filelist.size() && count <= 32;i++)
{
if(i==cursor)
pspDebugScreenPrintf("->%s\n",filelist[i].d_name);
else
pspDebugScreenPrintf(" %s\n",filelist[i].d_name);
count++;
}
if(cursor>count)
cursor=count-2;
sceCtrlReadBufferPositive(&pad,1);
if(pad.Buttons & PSP_CTRL_UP && cursor>0)
cursor--;
if(pad.Buttons & PSP_CTRL_DOWN && cursor<32)
cursor++;
if(pad.Buttons & PSP_CTRL_CROSS){
msg.ShowMessage("testpoint 0",0);
go=0;
}
}
msg.ShowMessage("testpoint 1",0);
I see the "testpoint -1" message. i can use the Up and DOWN button. But when i press CROSS it does nothing anymore. I don't see a crash report in PSPLink but i don't see the next message. Also without the message it stops responding.
I'm looking for some hour to this problem but i can't find a problem.
Can someone find the cause of that rpoblem?
Code: Select all
int main(){
SetupCallbacks();
makeNiceGame();
sceKernelExitGame();
}

From what I can see, once you press cross, you exit the while(go) loop and never render another frame... unless there is some code below that you haven't posted.

Well....
It's just a small part of a function. I see the first message "testpoint -1" but after i press CROSS it does nothing anymore.
This is the whole function:
Code: Select all
void CellManager::loadFile()
{
EasyMessage msg;
SceUID dir;
dir = sceIoDopen(".");
if(dir)
{
std::vector<SceIoDirent> filelist;
SceIoDirent entry;
while(sceIoDread(dir,&entry))
{
if(strcmp(entry.d_name,"EBOOT.PBP")==0 || strcmp(entry.d_name,".")==0 || strcmp(entry.d_name,"..")==0)
{
}
else
{
filelist.push_back(entry);
}
}
sceIoDclose(dir);
if(filelist.size()>0)
{
unsigned char count=0;
unsigned char cursor=0;
SceCtrlData pad;
msg.ShowMessage("testpoint -1",0);
bool go=1;
while(go)
{
GraphicsObject::endFrame();
GraphicsObject::startFrame();
pspDebugScreenSetXY(0,0);
pspDebugScreenPrintf("Files:\n");
count=0;
for(std::vector<SceIoDirent>::size_type i=0;i<filelist.size() && count <= 32;i++)
{
if(i==cursor)
pspDebugScreenPrintf("->%s\n",filelist[i].d_name);
else
pspDebugScreenPrintf(" %s\n",filelist[i].d_name);
count++;
}
if(cursor>count)
cursor=count-2;
sceCtrlReadBufferPositive(&pad,1);
if(pad.Buttons & PSP_CTRL_UP && cursor>0)
cursor--;
if(pad.Buttons & PSP_CTRL_DOWN && cursor<32)
cursor++;
if(pad.Buttons & PSP_CTRL_CROSS){
msg.ShowMessage("testpoint 0",0);
go=0;
}
}
msg.ShowMessage("testpoint 1",0);
SceUID fd = sceIoOpen(filelist[cursor].d_name,PSP_O_RDONLY,0777);
if(fd)
{
unsigned char tSize[2];
sceIoRead(fd,tSize,2);
msg.ShowMessage("testpoint 2",0);
if(tSize[0]>=20 && tSize[0]<=240 && tSize[1]>=20 && tSize[1]<=136)
{
msg.ShowMessage("testpoint 3",0);
char tGrid[tSize[0]*tSize[1]];
int tBytes=sceIoRead(fd,tGrid,tSize[0]*tSize[1]);
if(tBytes==tSize[0]*tSize[1])
{
initalise(tSize[0],tSize[1]);
clear();
for(int x=0;x<mWidth;x++)
{
for(int y=0;y<mHeight;y++)
{
if(tGrid[y*mWidth+x]=='1')
setAlive(x,y);
else
setDeath(x,y);
}
}
msg.ShowMessage("testpoint 4",0);
}
else
{
msg.ShowMessage("File corrupted",0);
}
}
else
{
msg.ShowMessage("File corrupted",0);
}
sceIoClose(fd);
}
else
{
msg.ShowMessage("Error opening file",0);
}
}
else
{
msg.ShowMessage("No files found",0);
}
}
else
{
msg.ShowMessage("Error while searching for files.",0);
}
}
Code: Select all
int main(){
SetupCallbacks();
makeNiceGame();
sceKernelExitGame();
}

This looks suspicious:
GraphicsObject::endFrame();
If you press X and you break out of the loop, it looks like there is still a pending startFrame() that might clash with the message drawing function? Just a guess.

It's just a sub-drawloop
Code: Select all
int main(){
SetupCallbacks();
makeNiceGame();
sceKernelExitGame();
}

I'd put a
Code: Select all
GraphicsObject::endFrame();
GraphicsObject::startFrame();
after every
At least then you know more about where you're getting up to. Failing that, are you running through psplink? Does it show the details of the crash?

PSPLink doesn't show a crashlog
Code: Select all
int main(){
SetupCallbacks();
makeNiceGame();
sceKernelExitGame();
}
