I'm not familiar with Patrick making such a mod, though I was gone for a while. I WAS just on his site recently and I didn't see such a thing. I know it was talked about by others before (making a Stinger mod for SA).


Here's the problems as I encounter them:•no if player defined check

•low priority loop with a 0 wait

•$7416 = 3; use custome labels, not DMA. I haven't bothered to check what $7416 is, but I know it doesn't belong to your mod, so you shouldn't be telling it to access it. By the looks of the way you use it later, it appears to be that mission's way of tracking a quantity. However, if you've never run that mission, the var is undefined and MAY crash the game.

•no need to loop the load requested models command

•but there IS a need for a loop to have a wait, a likely candidate for your crash

•your lumping of model readiness and keypress check is inaccurate. If you want the model to always be loaded when player is driving, then the keypress check should have its own check

•once you've added 90 to your angle, you should check if it's greater than 359.99 and if so, subtract 360 from it. However, my understanding is that the engine can handle angles grater than 360 anyways

•you have @1 capturing ground z, but @8 is what you used for the z offset, just as @8 is what you went ahead and used for your place Z value. It would be more accurate to change the line @1 = ground z to @8

•@9 and @10 are unused by your mod, so I'm not sure why there are lines setting them to anything

•your final jump jumps back to the beginning of the thread instead of the beginning of the thread's loop. So you're looping the name_thread command which there is no reason for and really shouldn't be done.

•you release the model even though earlier in the mod, you appear to wish to keep it loaded for as long as you're driving

•you've captured the car you're driving, but there is not a single is car wrecked check.

•last but not least, you're eliminating your stinger as soon as you plant it. I would think you'd NEED some kind of tracking system.


We've covered stuff like this before and I mentioned then that if you don't understand any of it, to ask. Should probably look more like (untested, with tracking only for a single stinger; more should be easy through use of array)

sigh.gif You already know how.


@Bear: Even if Patrick has done this already, there's nothing wrong with people learning how on their own.

You can't tell by reading the code? confused.gif Not sure I can help you then. Good thing I didn't try to make it support multiples first thing. Would've wasted a lot of my time.

Setting @9 to 1 when you drop a stinger accomplishes two things. First of all, it prevents you from dropping another since that code is only equipped to handle one stinger. Secondly, it lets the cleanup section of code know that the object has been created and needs to be relieved as well.
