I was trying to make a workable resizable display for a program I have in mind. I am obviously very new to allegro (5) and not yet that good in c++ either, that for prelimanary. so you may take that into account while answering if any!;D

Problem:

Above code works, wich ever display size I give in the top of the file, but when resizing the whole display just gets bigger with the window! And when resized, when reading out the display size:

int dw = al_get_display_width(display);
int dh = al_get_display_height(display);

returns the initial value wich I specified at first making the display1

What I want to get though is a display that where I have a map the size of whatever, say 20 times the size of the screen, that my resized window passes over the map and show a bigger portion of the map instead of what it does here, simply getting bigger or smaller letters.

In addition the way to continue should be when going with the mousepointer to NSWE(ast) on the map, that the remainder of whats on the map gets on the whatever size display.

To conclude, any tip on where to get better info on how to get up to speed with the various ways of reading out the functions, or learning to use them other then the manual, codingmadeeasy or Mike Geigs tutorial on the subject could be helpfull!

I did the tags (), thanks for answering, as in the code I remarked the al_acknowledge_resize already, wanted to implement it, but I stumbled on the fact that I cannot find anywhere a good example from wich to obtain the knowledge how to handle this. I have a hard time figuring out how to implement things from the manual only.

Many objects can just be pasted in and will eventualy come together in the program and are not dependant on if the screen question is solved as asked above, but it is part of the feature the end program will have to have or get stuck on a 800 by 600 screen!

Okey, got it.

Thank you for asking, search on....

So I hope there is someone that can help me, instead of telling me to tag my code and stating the obvious.

And to ad to my own 2nd post the question is more urgent then I lead to believe, not for that I cannot go try code other parts of the program, but that the existance of the lack of an answer holds me from freely coding that.

So thanks ahead if someone can help me out!

Well, you TRIED to use al_acknoloedge display resize but you aren't responding to the correspondent event.

To be honest, you aren't even chekcing the events apart for the exit button Keypress.

Is this too obvious?

Lenny told you rightly to go check usage examples, allegro example programs are a wealth of code, there's a HUNDRED of them and are toroughly documenting most library features.

Wait until you're not mad anymore and come back and read this entire thread again.

So hope we can get of that playing the man, and yep!

thomas told me pkrcel to go use al_acknowledge_display, with wich I got stuck and prompted me to ask the question in the first place! So the answer is useless to me and not adressing the question.

I gather it is from the onset 3 bits of code I dont grasp, but being honest in a lack of knowledge seams to lead here to being trolled.

Talking about attitude. If he doesnt want to answer the question why bother making more then the first post, I put the code tags in, I am new to this forum so didnt know right away how to handle that either. So thanks to Thomas thats remedied.

But if sending people on that are looking for an answer, a step up, and then telling them because he forgot the code tags, to go look elsewhere isnt the way this forum is advertised realy. Come to think of it, if making truely a clone of minecraft, he must have addressed the very same issue about the the screen as where my question was about part 1.

, so I appoligize, for understanding from your answer that you didnt understand that i was looking for the answer how to call that bloody acknowledge, since I now regret ever havin asked the question in the first place.

I tried follow codemadeeasy tutorial, jumped back and forth the last month between mike geig and the first mentioned tutorial, is in the first question to btw. And you may have noticed that having followed codemade easy tutorial that is quite a bit of effort, nothing ever is easy there these days since he retracted the code examples. Mike Geigs tutorial was a refreshing restart but without that, there is very little documentation about allegro 5, wich sparked me to ask about any place to find good tutorials!

I understand solving individuals problems with grasping how to implement this or that function is not mandatory, but looking at code is all I do these days. At least php, javascript and c++ are good documented, but I stil think that allegro can do much more easier what I want to accomplish on short term, and so I just need a step up from Mike Geig, since he handles lots of things, and maybe if codemadeeasy its website is up again can solve some issues.

Having followed Mike Geig I now can handle what he exampled, figured out the monitor part on my own, but yeah got stuck and learned that Mike and codemade easy always step over the realy interesting knowledge parts.

So yeah I know I lack knowledge, and yeah I am almost fluent in javascript, wich helps in understanding concepts in programming, but I just stumble in every new routine in allegro now.

Basicly you can say that if it was not in the Mike Geig tutorial I cannot use it, because Mike never explains the concept of handling it in reality, but just gives a good starting point.

So moving to close this thread to whomever is moderator. Its of topic!

Well now we are getting somewhere, , any particular source file you have in mind?

a link would be nice!

yeah thanks, looked at it loaded it, but thats why I asked here, since I already found not working examples by the dozen, one of the reasons I put in the top of my question: This file works.

Will try reverse engineer it even so,...

no bug, just common.c not included, so cant see a working examp.. One of the reasons I started writing snippets that work, if my collection is of a mature size it no doubt will be on my website someday. Going slow though gathering all examples, no one in my vicinity using allegro, and not much help elsewhere, yeah broken files...

The build system should let you compile the examples just fine.

You tried using allegro's cmake based build system?
