Re: iOS SDK: the same version as Xcode?

Dear community, I'm using LC 9.0.3 and 9.0.4 (RC2) on a Mac with MacOS Mojave 10.14.4. I wonder if I can use the latest xCode 10.2 that was released now in April, or if I have to go for the older 10.1? I guess xCode 10.2 is not tested for LC 9.0.3 or 9.0.4 (RC2)? On the LiveCode web page xCode/IOS F...

Re: Problem: polygon points moving/scaling 2x/4x ?

Thanks for tips Newbie, Two of the above mentioned solutions work. Just to clarify: When using lock screen/unlock screen, the screen is not always updated when calling unlock screen. On newer/faster environments on Mac, having many moving objects moving (e.g. >1000) at higher frame rates, unlock scr...

Re: Problem: polygon points moving/scaling 2x/4x ?

Looking at this further, looks like stacks are forced to keep the event handling open for the screen to be drawn when calling "unlock screen" for all environments. So my workaround is to use a standard game loop with "unlock screen" and a call like "send msg to me in x ticks". This seam to ensure th...

Re: Problem: polygon points moving/scaling 2x/4x ?

Studying this behaviour further, it looks like the screen is not updated when calling "unlock screen" in a script every time. In some environments it is updated every time I call unlock screen (MacBook Pro with LC 8.1.9) even up to 60 fps, but in other environments such as stand alone or a faster Ma...

Problem: polygon points moving/scaling 2x/4x ?

Dear community, I'm working on a simulation with many small particles moving around the screen. I'm using invisible polygons graphics to do this and the particles are represented by "marker points". It is working ok and as expected in the LiveCode IDE 8.1.9 on my MacBook Pro on MacOS El Capitan (v10...

Fast 2D graphics for games and simulation

I'm using Livecode to prototype a game concept where I require up to a thousand or more of tiny sprites moving around smoothly. A bit like particle physics. Livecode itself is very slow handling many sprites but up to now I'm getting by with a trick of using the anchors of invisible polygons as spri...
