it will depends on level (1lvl = 750hp what means about 4sec to kill, and it's per frame.

for(i = 0; i < DefNr; i++) //main loop, 0 to towers amount
{
	if(wieza[i] != NULL && !wieza[i]->isAttack) // if tower exist
	{
		for(b = 0; b < MobNr; b++)//loop from 0 to mob amount
		{	
			
			if(potfur[b] != NULL && potfur[b]->hp > 0) //if tower isnt attacking yet, the mob is not dead, and if it exist...
			{	
				oslDrawLine(
					wieza[i]->wiezaspr->x + wieza[i]->wiezaspr->sizeX/2,wieza[i]->wiezaspr->y + wieza[i]->wiezaspr->sizeY/2,
					potfur[b]->potforek->x + potfur[b]->potforek->sizeX/2,
					potfur[b]->potforek->y + potfur[b]->potforek->sizeY/2,
					RGBA(0,0,255,200)); // draws "beam"
					
				potfur[b]->hp -= 5; // hits it...
				wieza[i]->isAttack = true; // and make boolean isAttack true, so it shoudnt attack any other monster till this is death
						
				break;	
			}
		}
	}
}

I have only tided up the code a bit by removing redundant code and fixing the buffer overrun but logically, the code is sound. Your problem is more then likely to be else where.

Im nearly sure it can be done only with with this loop, problem is i dont know how...

[yaustar]

No, what I am saying is that your problem is probably not in the code that you have posted but somewhere else.

Upload all the code to the project and I take another quick look at it.

The only real issue I see at the moment is that you are overrunning your buffers.

for (i = 0; i <= MobNr; i++)

should be

for (i = 0; i < MobNr; i++)

Same with your other loop.

Edit: Another buffer overrun

if (MobNr <= 21)

And another

if (defs[(cursor->x - cursor->x%16)/16][(cursor->y - cursor->y%16)/16] == false)

[fiorello]

But any idea how to one tower can attack one mob till it's dead ? Now it attacks it once (-5hp) and nothing else.

[yaustar]

But any idea how to one tower can attack one mob till it's dead ? Now it attacks it once (-5hp) and nothing else.

I misread/misunderstood your original problem. This is the 'real' answer.

You need to reset the isAttack flag at some point back to false. Bear in mind that you may want to have a 'reload' time (a period of time between shoots) so it doesn't constantly attack the mob every frame. If you do want it to attack every frame, then just chnage the code so it doesn't use the isAttack flag.

		for(i = 0; i < DefNr; i++) //main loop, 0 to towers amount
		{
			if(wieza[i] != NULL) // if tower exist
			{
				for(b = 0; b < MobNr; b++)//loop from 0 to mob amount
				{	
					
					if(potfur[b] != NULL && potfur[b]->hp > 0) //if tower isnt attacking yet, the mob is not dead, and if it exist...
					{	
						oslDrawLine(
							wieza[i]->wiezaspr->x + wieza[i]->wiezaspr->sizeX/2,wieza[i]->wiezaspr->y + wieza[i]->wiezaspr->sizeY/2,
							potfur[b]->potforek->x + potfur[b]->potforek->sizeX/2,
							potfur[b]->potforek->y + potfur[b]->potforek->sizeY/2,
							RGBA(0,0,255,200)); // draws "beam"
							
						potfur[b]->hp -= 5; // hits it...								
						break;	
					}
				}
			}
		}

Hi,

When I want to start a .vbs script I get no VBScript-Engine was found.
I tried re-installing the Engine (microsoft.com) but it didn't work.
I need this also for Visual C++ because it needs it to create a new project.
Many thanks for the one who can help me.
I'm thinking of re-installing windows because I think my whole installation is f*cked up at the moment.
By the way, I tried copying the vbscript.dll files from the windows CD but the I got "CDBOOT: NTLDR Not found". But that's some other question.

Thanks:humped:

[72eco7V]

I'm modding my own version of nitePR rev J. I want to know if there is anyway to get the comments that are made with ; to show while your scrolling through your code and also that you can't select the comment (so it only highlights the actual codes)?

If there is a way can someone tell me or hint me as to how to go about finding and making it possible to show the comments?

Thanks.

[yaustar]

There is probably a section of code that ignores the comments when scrolling printing the text to screen or strips them out completely when copying to memory.

Do a search in all files for either:

";

Or

';'

And you may get lucky.
-=Double Post Merge =-
I found it already, it's in crt0_prx.c, line 5387:

     	else if(buffer[0]==';'){commentMode=1;if(nameMode){cheatTotal++; nameMode=0;}} //Skip comments till next line

You will find some knockons that you have to fix if you are going to display comments since it looks like you have to store them in memory and display them yourself from the looks of the code.

Yes i seen that part of code and there is more code dealing with the comments farther up in the file. but that one was mainly dealing with writing it to the new gamedir file

What are the pixel arguments in oslLoadImageFile? I know there's OSL_PF_8888 & OSL_PF_5551 but are there anymore?

[daaa57150]

If I remember correctly: OSL_PF_4444 and OSL_PF_5650. It's in oslib's documentation.

[InSaN3_GoDLiK3]

How would you write a delay/wait function for the psp? or/also how would you make a menu like in iR Shell were you can pick from icon and so on.

[slasher101]

Q1. sceKernelDelayThread(int waittime); arg is in microseconds
Q2. With a lot of work

[slicer4ever]

actually the second one isn't too hard, it's as simple as an array and going through that array, of course i haven't used IRShell, so maybe i misunderstand

[slasher101]

WooooooooooooooooooW you havn't used IRSHELL
