Re: EpicAsian's Dreamcast Endeavours:D

Hey guys, I know it's been a while, but I've finally found time to get some actually programming done!:D My question this time is an error when I'm trying to compile the DC Toolchain on Linux (Ubuntu to be exact). This is what my error looks like: cd gcc-4.5.2; patch -p1 < /home/tyler/dc/kos/utils/d...

Re: EpicAsian's Dreamcast Endeavours:D

I still couldn't get punchthroughs to work; as long as the translucent list doesn't draw as slow as DC SDL, I'm completely fine.

Re: EpicAsian's Dreamcast Endeavours:D

@nymus I don't know how to explain this but, I feel as though I have more control if I use the lower level part of the library. Also, I can only afford to burn multisession CDs at the moment. If I can get my hand on one of the Chinese SD card adapters, I would be a lot more productive. I'm currently...

Re: EpicAsian's Dreamcast Endeavours:D

What's the difference between punch throughs and translucency? Also, I don't think you ever answered my question about what is a polygon header on one of the first few posts, lol.

Here is a really crappy representation of what I mean:

Re: EpicAsian's Dreamcast Endeavours:D

About my post on splitting the screen: Take for example if you were writing a 2 player game for the PC. This game is a sidescroller, and you want both players to use one keyboard. How would you (if you even can with the PVR) split the screen in half so that both players can have their own "virtual" ...

Re: EpicAsian's Dreamcast Endeavours:D

How would I "uninitialized" a KOS Romdisk to remove it from memory so that I can initialize another? Would I do something like: ... KOS_INIT_ROMDISK(romdisk_boot); ... KOS_INIT_ROMDISK(NULL); ... KOS_INIT_ROMDISK(LevelOneRomdisk); ... Edit: Also, what util is used for texture compressing? And is the...

Re: EpicAsian's Dreamcast Endeavours:D

I did some more messing around and finally got it to work. The reason why it was crashing was because one of my purupurus that I was testing was dead.

Re: EpicAsian's Dreamcast Endeavours:D

I've tried mucking around with the rumble pack, and every time I call purupuru_rumble(), I get a freeze or a crash. Here is my code that uses the purupuru: maple_device_t* myPuru; purupuru_effect_t* effect; myPuru = maple_enum_type(0, MAPLE_FUNC_PURUPURU); effect->duration = 255; effect->effect2 = P...

Re: EpicAsian's Dreamcast Endeavours:D

So basically all I would have to do for animated sprites, is change the U/V values with a timer? What about multiple controllers? I've seen this post: http://dcemulation.org/phpBB/viewtopic.php?f=29&t=27922 And would this be the correct way to assign controller 2: maple_device_t *cont2_addr; cont_st...

Re: EpicAsian's Dreamcast Endeavours:D

When I looked at the texture_render example, all I saw was the code coloring the vertices; I didn't see loading an image and applying it to a poly. I successfully took the code from the png example, and created a basic player class with the coordinates, texture, and functions to draw, update and tak...

Re: Box2D on Dreamcast?

The only reason I was somewhat worried, is because when Box2D was ported to the 360, the performance started chugging at about 10-20 active physics objects. And I'm changing this thread to my DC dev questions thread, since I'm going to have a lot of them. I also have another question. I'm trying to ...

EpicAsian's Dreamcast Endeavours:D

I've been wondering if it is there is a port of Box2D on Dreamcast. One of my upcoming projects is physics based, and I would love to port it to the Dreamcast. The only problem I see with Box2D on the Dreamcast is the floating point math calculations. Also, if you guys know, is Box2D more optimized ...

Correlation between OpenGL and KOS PVR?

My question is, would it be beneficial to learn OpenGL and firmly grasp the concepts before using the Dreamcast's PVR? I'm coming from SDL and would love to use PVR but I have no idea how to begin to use it correctly or efficiently.

Thanks in advance,

Looking for a mentor.

Hey guys, As the title states, I'm looking for someone to aid me with Dreamcast game development. I'm not a complete newbie; I am competent in C++, and have looked through and studied the example Dreamcast programs. Somehow, when I copy the code from some of the examples, and put in my own file, I g...
