I'm trying to create a good working save script in my game, but something just seems to go wrong. When I start the game, I check whether the save file exists. If it does, I show two buttons, Continue and New Game. If it doesn't, I only show the New Game button. So far, so good. If you click New Game, the game starts from the very beginning, just like I told it to. All events in the game world work as well. But when I click Continue... a certain event (and probably even more as soon as I insert them) doesn't work any more. Also, when I run it in Debug Run and then click on Continue, I get the message: Error E1513 - Crash in Event. These are the pieces of code which should take care of the Saving and Loading:
continue_handle = file_open_read("my_save1.SAV");
if (continue_handle) {continue_pan.flags = VISIBLE;
file_close(continue_handle);}
PANEL* save_pan =
{
pos_x = 0;
pos_y = 0;
layer = 1;
button(0, 0, save_bmp, save_bmp, save_bmp, save, null, null);
}
function save()
{
game_save("my_save", 1, SV_ALL);
}
function continu()
{
while(key_any) wait(1);
game_load("my_save", 1);
wait(-1);
}
This is the action() that's not working any more after loading the game.
action grass()
{
my.emask |= ENABLE_IMPACT;
my.event = battle;
}
function battle()
{
if(event_type == EVENT_IMPACT)
{
battle_var = integer(random(101));
if(battle_var == 100)
{
gevecht();
}
}
}
I tried asking in the liteC part of the forum, but there was no one there who could help me.

There was mention of save / load problems (bugs) for some version(s) of the engine. Are 'you' using the latest version of the engine? *check return value of game_load? --does the load fail outright? *check format of button function? *function not declared prior to use? *superfluous while(key_any) wait(1); ? *block inappropriate repeat calls for continu? (already mentioned) *save / load incompatibility with modified scripts / level? (already mentioned) *DYNAMIC flag? Save Error (previous thread)

Quoting a version of the manual:
game_load(STRING* name,var num)
Loads a saved game in the savedir folder.
...
> 0 - successfully loaded, <= 0 - file couldn't be loaded.
var bSuccess = 0;
function continu() {
bSuccess = game_load("my_save", 1);
// if (bSuccess == 0) { // failed outright }
}
// different format of button function
function continu(PANEL* _p, var _buttonNum) {
}
Quoting pegamode. Thanks for publishing version 7.66.3 ... I was wondering why my savegames don't work anymore ?!?
With 7.66.3 everything works fine again. The issues might be unrelated. (Bah, 'I' don't even really use Lite-C / A7...still using A6.)

Well, the game does load normally, but the action attached to my model doesn't work any more. So in this case, bSuccess equals 1 after loading the game, cause the load itself is successful. This is the panel I used for the function:
PANEL* continue_pan =
{
pos_x = 30;
pos_y = 10;
button(0, 0, continue_bmp, continue_bmp, continue_bmp, continu, null, null);
flags = VISIBLE;
}
It has a size of 580x118, but I don't think there's a problem with the panel, cause the function works and all, but the action doesn't work any more. I'm using the latest version, not a beta version. So it's the version I got from the download page.

If I were to change var into var_nsave, it gives me an error message: 'var_nsave' undeclared identifier.
I think continue_handle is indeed saved in my_save1.SAV, but that simply can't be the problem. Cause when I start the engine, it's value is set to a positive value if the save file exists or to 0 if it doesn't exist. If the value is positive, I can press continue. And when I press continue, the value (which should be zero) is loaded from the save file, but that doesn't matter, cause continue_handle is of no use to me any more after I load the game.
I checked all the flags of my model in my WED, but there's not a single one called Dynamic...
Edit: For some reason, the previous post I was replying to, has been deleted...

According to one version of the manual, var_nsave is replaced by a suffix of _n.
var continue_handle_n = 0;
That is, any var with a name ending in _n, might NOT be saved by an invocation of game_save. Of course, as expected, that might be consistent with the current trend of absurdity (=correctness). Feel free to do a search in some version of the manual for term "DYNAMIC", or don't, that's OK too. On a more or less relevant note: Perhaps, it was suggested that jcl would be 'out' for a week, but maybe not. 'I' am not one of the developers from the aptly named forum category "Ask the Developers".

Well, my model has an action attached to it, so it should be DYNAMIC, right? And when I use game_save, any DYNAMIC entity should be saved. So when the level loads with game_load, the DYNAMIC status of the entity should be loaded as well, am I not correct? I tried setting the DYNAMIC flag for the entity after loading using:
grass_ent.emask |= DYNAMIC;
But then when I touch the entity, it gives me an error message: Crash in Continu().
