Hello. I'm new to GS and this is my first post so I hope I'm putting it in the right place. Anyhow, I'm working with the A7 Demo and creating an adventure type project (3rd person) and using the day/night script by loopix. I keep getting this error while running the game. Crash in flare_place:(c_trace(camera.x,temp2.x,trace_mode)!=0) which is the modified lflare wdl.
Does anyone know a fix for this? I've tried playing around with the camera clip distance and everything else and keep getting the same result. It happens during run time at random. Usually when models are between player biped and the sun panel. Please let me know how to fix this if you have any insight. Thanks very much.

Sorry, I forgot to post this info:

What do you mean with "the modified lflare wdl."?

This is the comment in the lflare1.wdl script file which is used in place of lflare.wdl There are some minor modifications in the script file in order for it to work with the dn_cycle.wdl script


// Modified Template6 file (by David Lancaster and Loopix)
////////////////////////////////////////////////////////////////////////
// File: lflare.wdl
// WDL code for lens flare and lighting effects
////////////////////////////////////////////////////////////////////////

(I hope this all makes sense lol)

Post the complete code or demo of the script that cause the error. I have Loopix day/night code working. Don't know anything about lflare.wdl though.

code from lfare1.wdl (problematic function is highlighted in red) Hitting ok will temporarily resume the game until it happens again (which is until the player moves a little bit at a time out of the inflicting area).

Looked at the sample and updated the code a little, but I did not receive the error. Try: download, does it work?

Thanks, it works fine in the demo level you posted but still the same result when running my program. It's not a random problem as it seems that it only happens when between certain objects and the sun. The level I'm using has quite a few models/entities in it. Also, it seems to happen more in the daytime than anytime else. Here Detail image is a new image which I hope will explain more.

woohoo. me thinks me got it. added ignore_models.
trace_mode = ignore_me + ignore_you + ignore_passents + ignore_passable + ignore_sprites + ignore_models+ scan_texture + USE_POLYGON;
Haven't had problems since and gained 5 - 10 fps

I hope this can help anyone using this script!
