3D Objects in Game Editor

[tintran]

edit: moved some arrays definition from displaywire() to global and solved the memory leak, weird I thought that functions automatically handled memory freeing of arrays that are defined within it.

This pretty much only happens within GE, happened to me before
When a game closes from within GE, I don't think it clears any memory

Good to know.
The weird part is that that function is called everytime the model rotates a little, so 18 times happens all the time when it's running but it won't cause that error.

I think it uses the same memory space every time it runs the function, but then it would need to allocate the already allocated memory.. perhaps it just allocates it once when GE compiles the function? GE doesn't seem to follow the same scoping rules as in normal programming. Though I can't be too sure about this since I don't know much of how GE handles with variable, only that it's buggy if you know how to abuse it.

what's a good way of letting user type in a file name and then they hit Enter i can load that .obj file?
I tried using GetKeyState() but the typing seems buggy to the user experience when 2 or more keys are down.

[skydereign]

I usually use an any key down event, and use getLastKey and a switch statement (default adding a character defined by getKeyText). The specified cases for backspace, and shift, and perhaps adding an escape.

personally, a text input actor is much simpler to use I find

[tintran]

oh now i feel like an idiot that that's already built-in too

Hey, I have an idea. I havn't taken a deep look into your code so I'm not sure if this will work or not. You could try loading a series of .obj's instead of just one and displaying them as frames of an animation. Like you could have an array and you could have the canvas display one .obj and then the next etc. Would that work at all?

[skydereign]

That would work for animations. I did that once using just pixels in canvas (importable animations), but the actual use of this is currently severely limited by the canvas's efficiency. And the reason I don't use the built in text input is mainly due to the repeating keys. But then again, I already have a base ged for mine so I just merge it into a game.

[SuperSonic]

@Sky: Cool. I like to do stuff like that too. Make a lot of code an save it as a ged template. Then just merge it

@Tintran: So are you gonna try animations?

[tintran]

I don't think i am going to try animations. It's already slow. plus i think i would have problems coming up with the models that represent each frame.

[SuperSonic]

It doesn't run slow on my computer. Plus, I can come up with some basic animations for you (like animation cessna.obj)

[skydereign]

Actually making the animation to work only takes a little bit of string manipulation so you could probably do it yourself, and moving the wirefromfile function into something that repeats. If you set it up right, then you only need to redraw the wireframe every time you want to change the frame, and since you aren't rotating it will generally be fast enough.

[tintran]

@skydereign: you're right.
@SuperSonic: let's wait for your basic animations, right now i only have examples of static models.

This just keeps getting better. the performance is NICE too!

Now if only you could possibly get it to be in full color and texture probably using something similar to the BMP Loading thing that DST made, but heck I wouldn't have the slightest clue how, or how you did this for that matter. I tried reading your code and got super confused haha.

Your an amazing programmer, your going to make awesome games in the future.

Here is a simple 10 frame animation of a chest opening. I can add more frames to it if it looks sloppy or anything
