| Summary | 0002997: In game crash on missing weapon trail, should be caught during parsing? | ||||
| Description | I was experiencing crashes and decided to debug, to discover that the crash was caused by a ship firing a weapon, debug threw this message at me: ASSERTION: "ti->texture.bitmap_id != -1" at trails.cpp:193 Weapon trail could not be loaded Int3(): From d:\fso\scp - clean\code\globalincs\windebug.cpp at line 1040 After some puzzling I discovered that the weapon table entry was missing +Bitmap: under $Trail: my mistake but, Shouldn't this be caught during the initial game load (as 99% of other table parsing errors are) and not cause a ingame crash instead? | ||||

Should +Bitmap be made required? I don't see how you can use a trail without a bitmap so making it required should fix future problems. |
|
|
Making +Bitmap required seems like a good idea. |
|
|
Yes, it's pretty clear that +Bitmap should be a required table item if a weapon trail has been set. The remaining +Trail items can all be set to default values by the engine, but this section of code/weapon/weapons.cpp shows that the Bitmap will be set to NULL (leading to Assertions() later on). https://github.com/scp-fs2open/fs2open.github.com/blob/master/code/weapon/weapons.cpp#L912-L920 Interestingly, +Bitmap has been an optional item ever since the Weapon trails were established as part of extensible tables in 2005 by WMCoolman https://svn.icculus.org/fs2open/trunk/fs2_open/code/weapon/weapons.cpp?r1=2268&r2=2283 |
