Hey SDK users

Seems quite in this forum? I guess everyone is doing the same as me, i.e. sat down with a C++ book

Seriously, anyone up to anything that's going to show off the SDK? Or.. any dates for the next update?

p.s. while I'm here, does anyone know how you print out hoe many objects are in a list using dbText? i.e. I have a list (via the joys of STL) of game objects and I want to know how many I've spawned. I loop the list using an iterator, something like this..



..and I tried to do dbText(10,10,dbStr(objlist.end)), but I don't think the .end can cast to a string. But then, I'm new to this Maybe there is a total or size thang that I'm missing.

Cheers in advance!

hey Lampton i am pretty new aswell, but wouldn't you use

dbText(10,10,dbStr( objlist.size() ))
size will return an int and should have no problem converting to string with dbStr.

now if you want to print out each object you would use the code you posted.

can anuone else say this is right.

Why don't you use a factory to spawn objects and use a field in it to keep track of the number of objects? Don't forget a method to decrement the count when things die (if you want a count of active objects rather than just the amount spawned).

Ah, don't you just love the C promotion rules?

Basically, objlist.size() returns an 'unsigned int', and there is no dbStr() function with an exact match. It can't choose one, because there are two equally plausible choices ( dbStr(int) and dbStr(float) ) and either one will cause a loss of precision in the conversion.

Try 'dbStr( (int)objlist.size() )'

@Troll Fiddler, yup that was my next move, however IanM's suggestion worked a treat.

Cheers both
