How to draw simple rectangle

Posted: January 26th, 2013, 4:16 pm

I'm slowly understanding how to code for the ps1, mostly by looking at other peoples' source code. I'm yet to find out how to draw a simple 2d rectangle, something like this:

fillRect(Xposition, Yposition, length, width);

Anyone have some simple code that will achieve this?


Thanks

Just make a 1x1 pixel as a TIM, and use code to stretch it and position it on the screen where you wish.
It will also allow you to also use more features, such as rotation and colour shading.

I know that may sound simple to you, but I (just starting out in ps1 dev) barely know what a TIM is, let alone how to use one.

I'm using ot_example.zip from http://www.reocities.com/timessquare/ch ... ource.html as a guide.

It just draws a starfield which is just little rectangles - pretty much what I want to learn.

Okay, I will make a TIM example for you. Give me a few minutes...

All you will need to do is load up TIMTOOL and add the included TIM into it.
You will then see where I have positioned it in the framebuffer, and how the code makes sense.

Here you are (followed the PSXDEV.net comment layout):
timexample.zip
Just use CATFLAP or PSEXE.COM to upload it to your PSX (unless you are using an emulator).
Use Psy-Q to compile it. Make sure you upload 'image.TIM' to '0x80025000' before loading the PS-EXE.

If you want to include the TIM in the PS-EXE so you don't need to upload it separately (because you're using an emulator for development), you will need to include it in the compilers MAKEFILE as an object or header file. You will also need to change some code for it to work if you do it that way.

Thanks for the example, sadly I'm using an emulator so I can't run it.

Why is using a TIM better than the method in ot_example.zip? Only the added things like rotation and shading? If I wanted to make a game that only had a 320x256 grid of pixels, would the ot_example.zip way of drawing be okay?

It would be alright, but it is a lot more hard work and it is a bit more complex.
The TIM method is just easier to control and use.
Though, by using your method, you would save a tiny bit of RAM and give a significant speed increase.

See this code (old code): http://www.geocities.co.jp/Playtown/200 ... ly2d.c.txt

I'm stuck again :(

All I want to do is draw with double buffering:

setRGB0(&(player.tile), 0, 0, 0);

AddPrim(1, &(player.tile));

where player is TILE_1

check out the PSY-Q sdk pdf named "LIBREF46.PDF"
you have a bunch of ready to use functions like GsSortBoxFill to draw a rectangle

I have a little playstation lib that I made on top of psy-q sdk, it's not state of the art code, but it can help to code easier.
I would need some time to make a tutorial on how to use it and release it, it could help some of you

Re: How to draw simple rectangle

Posted: April 20th, 2013, 12:00 pm
by inc^lightforce
.... I'm yet to find out how to draw a simple 2d rectangle, something like this:
fillRect(Xposition, Yposition, length, width); Anyone have some simple code that will achieve this?
And here comes the 2D RECTANGLE CODE: NO GFX USED -> only Code.
