An oldie but a goodie: recording the screen!

Hello all, hello hello hello.

So I've seen this done a million times in DIV games before, and I'm sure you all have as well Where ingame, there's a TV screen or a display of some kind which shows exactly what the player's looking at, using the screen_get function.

I've got it working just fine in CyberCrisis at present, except that every now and again, it causes a random crash - the game will quit and I'll get the "blabla has encountered a problem and needs to close" Windows box pop up.

Before the loop/just after the Begin, I have this code:

displayscreen_graph=map_new(73, 55, 16);
playersscreen_graph=screen_get();
map_xput(0, displayscreen_graph, playersscreen_graph, 36, 27, 0, 15, 0);
graph=displayscreen_graph;

and then in the main process loop, this code:

playersscreen_graph=screen_get(); // Crash
map_xput(0, displayscreen_graph, playersscreen_graph, 36, 27, 0, 15, 0);
graph=displayscreen_graph;
Frame;

For some reason, the line I've commented with "Crash" makes the game, well, crash. Commenting it out/removing it and running the game works just fine (except the screen doesn't update beyond the first frame of course).

As it's been done so frequently in DIV projects, I wanted to ask if anyone here had any experience with it, any why this might be crashing the game?

The game's very near completion and it's a blast to play, I'm sure you'll enjoy it when it's done

Right, I've gone over to the Bennu forum to ask them about it Other people do seem to be using it, just not in the same capacity as I am, so someone'll likely know something.

I doubt porting CyberCrisis to DivDX where the screen_copy function works would be plausible sadly, as it's all 16 bit and relies heavily on additive blending. :/

Phew, got it fixed. Turns out that screen_get loads into the system memory, so you need to UNload it after every use, haha. Done and done

Ah that makes sense

So, we might be supporting the bennu 32bit fpg format soon, would make returning to the DIV stable a bit easier

Brilliance! All I'd need then is a Mode 8 map editor with a few features like copy paste & selection boxes for multiple vertices, and possibly for it to not crash every other time I right click... or to randomly make undeletable vertices and sectors which crash the program and corrupt the .wld file... haha. But a 32bit FPG format would be great

Right clicking often causes the editor to crash, on windows 8 at least. Occasionally when making lots of smaller sectors for things like little pools of blood or rock formations, I end up with one bad sector that ends up being unselectable, so I can't delete it - and when you attempt to view it in program, it crashes DIV entirely.

Selection boxes and copy paste would be so powerful - you've made a room too small? fine, just click and drag to make a selection box, select all the vertices of the top of the sector, then pull them all upward at the same time, allowing for easy and effortless manual expansion of the sector, or sectors. Hm, it's still looking a little barren... I know! Let's copy that "crate" sector from another part of the map... hit paste three times, then position the three new crates where I want them. There! (An ability to rotate a sector with all it's vertices moving at the same time would be good for this, too. You could turn them on their axis.)

All just ideas to make the editor more friendly and encourage further use, of course
