[TEC] Getting rid of the hardcoded reticles (Yes, it can be done!!!)

When I consider how simple the solution was, I feel almost stupid for the time (years!) it has taken to figure it out :damn:

I guess I'll never get accepted at MENSA ... oh well :haha:

On to the topic:

THE PROBLEM:

As most modders know, the reticles seen in the periscopes and UZO in SH3 and SH4 (german uboats, not american ones) are hardcoded and can't be removed away. This has given more of a headache to the modders who wanted to change the look of the reticles, because the old ones would still show, no matter what. The only solution we found for this was to reduce the field of view, and make it smaller than 30º for the periscopes (Because the graticle leaves a space of approximately that size in the centre, where you only see the crosshair). But that of course meant losing field of view at the expense of historical reality, where periscopes had some 38º (In the game it is 40º)

THE SOLUTION:

Well, as you also know, when you zoom in with your mouse wheel, the hardcoded reticle does NOT change its size. It is scaled to display in the proper size of the default zoom you have, which is usually 1.5x

Soooooo :DL if you think that the high power zoom is way less than 30º (Normally 8º-9º) and will as such never show the reticle ....

the simple solution is to INVERT the order of the zoom levels in cameras.dat, making the high power (6x) the default one (First zoom entry in cameras.dat), and the low power (1.5x) the second one (Second zoom entry in cameras.dat) you get when moving the wheel mouse. That way, the reticle is scaled to the 6x default one, and actually is moved off the screen, leaving only the central crosshair :yeah: And you won't see it either when switching zoom to low power, because it doesn't rescale :woot:

That's it gentlemen :rock:

Following Hitman's instructions Peabody made a new camera view for the IJN scope type 88 :

Thanks to both of you guys !!!

At last, a type 88 perscope view !

So it seems the actual US periscope view with the azimuth might be mistaken !!!!

Yes it is indeed, we already discussed that some time ago.

The commander looked through the scope and when he called "mark" the assitant on the back of the scope readed the bearing from the azimuth circle, and the distance from the wiz-wheel. If you look at the design of the US scope you will notice that it was built purposedly for having a second person assiting while the captain was looking through it - the wiz-wheel is at the back of the scope!!

Quote:

204. RANGE - MARK: A phrase which when used by the Approach Officer during a periscope observation directs the Periscope Assistant to read the stadimeter or telemeter range and informs the Fire Control Party of the time of the range. When spoken by the Radar Operator it indicates that the radar is on the target and the range repeaters are reading correctly. It is usually paralleled by a buzzer and a mark light in the latter case.

Quote:

Approach officer Bearing ____ Mark! Down Scope Periscope Assistant On bearing _____ Mark! rings the bearing buzzer or if the bearing transmitter is out of order, announces the bearing. Lowers the periscope.
