Hi,

It would be really nice if we had the ability to add values to sprites, for instance if I wanted to store the health of a sprite I could do something like:



I'm currently doing this manually by scanning through my enemy array and finding the enemy with the sprite ID and checking the health. it's more of a nice thing to have, not essential but things like this make life a lot easier for T1 developers.

You need to do a sprite manager with arrays.
Define your type and add the values you want.

Long life to Steve!

This is what I currently do, I have an array of different enemy types, all have their own UDT, which contain a common UDT for global properties. However, say I have 10 different enemy types on a map and there are 10 of each enemy type. That means potentially I have to iterate over 99 array items in 10 different arrays to find the one I'm looking for.

This is inefficient and not very wise. There are other hacky ways to get around this, but they are just that, hacky.

Having an arbitrary attributes/properties tag on the sprite would be ideal. However, as this is not likely to happen, hacky it is!

i had requested long ago a reference "id" as integer in sprite struct.

my idea was:
SetSpriteReference(nSpriteID,index)
index=GetSpriteReference(nSpriteID)
blah[index].health

It's quite easy in C++ or Pascal, because you can sub-class the sprite type.

I've been thinking about moving over to T2 quite a lot recently. The only reason I've stuck with T1 is that it is super easy to port onto the different platforms, I can also test it on my phone in a couple of clicks.

How hard is to port the code base from Windows to Android and eventually iOS? I'm under the impression that if I stick to the AppGameKit commands and only use libraries that are themselves cross-platform it shouldn't be much hassle. It will be just a case of copying my headers and source files into the new target project, is this correct?

P.S. I have absolutely no desire to use Pascal, I would personally rather chop my hands off and type using my forehead on a keyboard where the keys are rusty nails C++ I used to use on a daily basis a few years ago, so I can move over to this if it's not too much hassle. Due to work and life commitments time is of limited stock, so I'm trying to make this project as painless as possible.

Good luck, then. Stick with ghastly. Ignore the better.

Like I say, C++ would be the way to go for me if it doesn't add too much to the time it takes to port the game to the various platforms. I might give a try tonight and see what it comes up with. I have asked the question about ease of portability in T2 (C++) but I have yet to get an answer, fingers crossed.

I must admit, loosing OOP functionality is a big hit, I'm so used to using it now it feels like I've been handcuffed.

I surely second this.
I needed it for every project until now.
I don't think several different properties are necessary.
If the sprite returns a number you can in index in your own array of UDT´s for any associated information.

I work in Tier 2 and use the same code in all platforms without an issue. You just have to set up projects for each platform.

If I ever can find the time, I'll finish the tutorial I had started (built into one file which was too large and needs to be broken up) and it shows how to do a lot of cool stuff in Tier 2, including using one set of code in all platforms.

This may be a little easier with v2 and being able to pass arrays by reference. But there's still a lot of possible overhead.
I wouldn't get your hopes up for additional commands like this, Paul's pretty buried with everything for v2 from what I can tell. There doesn't seem to be much room for him to do added functionality beyond what is planned for v2 (which a lot of it we're in the dark about).

I'm gearing toward t2 myself because I need a lot more control over my apps and I need the ability to add in SDKs like Google Play Services and extend/fix the capabilities in existing SDKs (FB , Game Center , IAP).

@AL - would you be interested in sharing your tut as it is right now? I mean many of us might have to fumble through, but that's better than nothing. I just spent 3+ weeks on and off learning java stuff so I could implement Chartboost with T1 (and it works!). So I think I could grasp the C++ stuff with a template of sorts.

If it's any motivation, I'd find that tutorial extremely useful.

I actually had it complete and Paul looked at it. But the resulting page was way too long.

So, my effort now (when I can make the time) is to logically break it up into multiple pages with a top level one. I have it started, but have been busy with the new full time job.

<-- Only job is to make games
If you want to pass it along to me then I could take a stab at it

Thank you for the offer. But I think this is something I need to finish myself.
