[Not a bug] OpenGL bug with dynamic lights

[kfpopeye2]

Not sure if this is a bug but...

I have the following object defined in GLDEF:

Code: Select all • Expand view

object COLUMN_1
{
    frame COL1 {light LIGHT_COL1_1}
    frame COL1A {light LIGHT_COL1_2}
    frame COL1B {light LIGHT_COL1_3}
    frame COL1C {light LIGHT_COL1_4}
}

the lights are just simple point lights. Then I have the following states in the actor class:

Code: Select all • Expand view

States
   {
      Spawn:
         COL1 A 1;
      IdleOn:
         COL1 ABC 1;
         Loop;
   }

The problem I have is the 3 frame bound lights are always flashing. I would have thought that 1 tic would be too fast to see the lights turn off but it isn't. Am I missing something?

Please post a runnable example.

To me, at least, the effect you see is normal. Think about it for a bit: each of the three sides of the column is lit for 1 tic (~0.028571 seconds) and is unlit for 2 tics (~0.057142 seconds). That would create the light flickering effect you see, wouldn't it?

I'd think the flickering would be too fast for the human eye to see. I could be wrong though.

What makes you think it's too fast to be seen? No, sorry, this behaves exactly like intended.
