Got fire to run but won't reload level, problems.

| Hi, I'm still trying fire. I finally got the basic effect to load and run but now it won't allow reloading a level. I use f1-3 to start sections of a game. The code won't allow restarting a level, after character dies, or returning to a previous section. In section 1 you can still go to section 2 or 3 but not back to 1. The update_fires was causing the first problem with memory access violation. I put it in a loop that only calls it when fire is showing. It now finishes the level. I guess you can't update something that isn't there. I lose so much control with the effect I would like to improve on it. Any help available?

The level select switches f1-f3, o restart level work but the memory access violation message comes up if you try to play the level. This is only on going back to a level previously accesed. In level 1 you can select level 2 or 3 but you cannot go back to level 1. This means you cannot restart the level if your character dies. The game must be restarted completely. Why can’t the levels be restarted? (Or go back to a level?) |

| Hi, Because the tfield costs so much function (reloads, restarts) and I cannot do it well I'm using a wings 3d snow entity and pivoting it at the camera. createpivot piv(camera) snow position camera rotate camera pitchyawroll trunentity piv,.3,0,0 Let me know if you can figure out my mistakes and correct them or advise me on tfields.

| You have 112 forum posts - but still have not had the time to take a look into the forum codes? Why don't you put your code into code or codebox? This way tabs are kept - code is blitzcode and not changed into html, aso aso aso ... |

| Hmmm.... Lemme try and help out. I'm having a hard time following the flow of this program - I suck at reading code that I didn't spit out. Ah, well. :P Anyways, from what I can tell, you have a system that flows using labels. That's your first error. Well, it's not really an error, but it still makes debugging and running your code a lot more painful than it needs to be. Instead, try using a main loop that initiates after the buffer is set. Have a global keep track of your game state. Select the global in the main loop, and do stuff depending on the state. At the end of the loop, you can update the game state, so that it responds to keys 1-3 being pressed. Oh, and, yeah, following RGR's tip helps A LOT. Tabs really do help with readability... |
