I am new to DarkBAsic Pro, and was interested by something it said in the manual. It said that the number of lights you can have at one time is dependant on your accelerator card. DBC could have only a maximum of 7 lights, so I wanted to see if I could now have more. I used the function GET MAXIMUM LIGHTS() and it returned -1! Has this happened to anyone else? Is this a bug, or is it just my system?

but you should try to make several lights and look if it works

for i=1 to 50
make object sphere i,rnd(10)
position object i,rnd(50),rnd(50),rnd(50)
next i
autocam off
point camera 25,25,25
for i=1 to 1000
make light i
color light i,rgb(rnd(255),rnd(255),rnd(255))
position light i,rnd(100),rnd(100),rnd(100)
set light range i,300
repeat
a$="Light number: "+str$(i)
text 200,200,a$
sync
until upkey()
wait 100
for l=1 to i
if (light exist(l) <>1) then text 200,300,"light missing"
next l
next i

I gave up at 240 ????, anyone care to try this?

I think almost all cards have 8 hardware lights.
It returns 8 on mine, are you using the demo version of dbpro it has a fair few bugs.

Mentor, I got up to 1000 using that code. Get maximum lights() returns 8 on my computer, I've heard of people getting -1 before, but can't remember why.

I suspect it is re-using lights but why does the check never flag any lights as not used?, I am sure if my card was trying to render the effects of 1000 lights all at the same time then fps would be down to .02 per second , seems like the values are just rolling over and there is no limit check in the function (or it uses get maximum lights to work out the limit), so you get up to 8 lights and then it rolls over (ie: 9=1 10=2 11=3 etc) but I still can`t figure why light exist says the other lights exist, unless that is rolling the values over too, either that or some people realy can have 1000 lights .

Probably because "make light" sets-up all the parameters for your light in the scene (position, colour, type, etc). So yes you can have as many as you like, in a way it's just setting them all up ready for use. The limit is in how many of them are actively visible at once, typically 8.

Cheers,

Rich
