[Can't Use box2d with ultra app kit]

woops, never mind my fault i got it working now

[Can't Use box2d with ultra app kit]

they simply won't work together can't even compile because MDd_DynamicDebug dosent match MTd_StaticDebug in main.obj and if i try to have them both the same to avoid the error then appkit complains the same and visa versa any way to avoid this or am i just stuck with this.

[In-window IMGUI stops refreshing]

it's because your embedding a window inside a window and it looses focus. One way to get around this would be to add the mouse click "left down" so the code would be in the while loop but before the event stuff.

        if (viewport->MouseDown(MOUSE_LEFT)) {
            viewport->Activate();
        }

[cant get the tutorial to work https://www.ultraengine.com/learn/CPP/Leadwerks]

16 minutes ago, Josh said:

You start with a Leadwerks project, not with an Ultra App Kit project. The pre-made project here is updated:

This expects you to have Steam installed at "C:\Program Files (x86)\Steam" and Ultra App Kit and Leadwerks installed in the default locations.

If Leadwerks or Steam is installed in another location you can edit the file "Projects\Windows\PropertySheet.props" to indicate the new paths.

everything is default both leadwerk and steam are in default steam locations

Fixing this now...

it can't find leadwerks.h file still

steps to reproduce:

download example project

open sln with vs 2019

build solution

error can't find leadwerks.h

 

here is a screen grab of included directories for me with that project:

[cant get the tutorial to work https://www.ultraengine.com/learn/CPP/Leadwerks]

the default paths in the app.h are wrong for the steam version also for leadwerks.h cant find file any help with this. using vs 2019 everything is the default and i have used the example project whats gone wrong with this.

thanks josh i own leadwerks on steam too great stuff. i guess use opengl render for the sprite drawing for a basic 2d platformer?

[App kit - any recommendations of easy to intergrate 2d c++ engine libs]

Hi,

have a few general questions. I bought this on steam does that mean i own it forever or is it a rolling payment? also wanted to have a go at a basic 2d engine opengl based any recommendations.. i only just purchased this.

thank for any and all help
