Re: Optimization issues -- How do I keep my game from lagging?

Ohhh. That makes sense, I had optimized it for 1 model, the map one that you would've seen commented out, so that made sense for just 1 model, but not tons of individual ones.

Re: Optimization issues -- How do I keep my game from lagging?

I can't tell about the performance; maybe check with a profiler. I've seen trigonometry used where none is necessary (it's sadly usual to see how people take the atan2 of a vector then the sine and cosine in order to just normalize it, spending three trigonometric functions where just two multiplic...

Optimization issues -- How do I keep my game from lagging?

To be specific, I'm creating a TON of objects, and I know rendering isn't the issue as I have it rendering only in a very small area at a time. And GC goes insane when it launches. How would I fix this?

Also, here's my .love file if it's relevant:

Also, I'm using the G3D library.

Problems with .mtl parser, only 1 material gets applied to rendered shape

As I said in the title, I'm writing a .mtl parser and for some weird reason, only 1 material gets applied to my 3D rectangle. I have no idea if it's my graphics code, or the parser.. Here's my .love file (Warning, spaghetti code ahead!) Game Name.love The relevant function(s) are drawShape3D in grap...

[SOLVED] A table is nil and not nil at the same time??

As stated in the title, I have a problem where a table, if I try to print just the main table (Recursive tables), it prints fine. If I try to access anywhere in the table, it's suddenly nil. Even when I set that index to always be 1, it's still somehow nil. Here's my .love file: Game Name.love The p...

Re: How would I write an algorithm to convert a OBJ face to triangles?

Some general pointers, may or may not apply to your problem: A quad on a plane is trivially converted to two triangles 0---3 | | 1---2 { 0, 1, 3 } is triangle #1, and { 1, 2, 3 } is triangle #2. In your cube example you would ideally represent this as an indexed triangle list, to keep the number of...

How would I write an algorithm to convert a OBJ face to triangles?

As the title says, how would I write an algorithm to convert a OBJ face to triangles? Example: You have a cube.obj file that has 6 faces, but they have 4 vertexes (Per face), and you can only render in 3D triangles. How would you convert the data to a set of points and lines defined as the points to...

Ah. Yeah, that was supposed to be there.. Thanks!

Help with OBJ parser?

I'm currently attempting to write a OBJ parser and it's not outputting anything but the 1st variables in the v and f lists.
This is a really simple parser, and I have no idea why it isn't working properly..
Here's the .love file:

The parser is in the objParser.lua file.
