Simple title screen

[mdkdue]

Hi everyone

 

Can someone please point me in the direction of some example code to generate a simple title screen where i can simply display an image and have the option to 'Press A/B/C etc to start' and then have it run my program?

 

At the moment when i launch my project it just jumps straight in, it would be nice to be presented with the name.

 

I looked in the guides and couldnt see anything to help me.

 

Thanks in advance.

There's a title screen in the doger project that comes with JagStudio

There really is not much to see at the moment to be honest, just a background and some sprites. 
 

I am using the example projects as my starting point so I guess you could just call it a reskin.

Thanks for this.

I had a look, and whilst i understand what it is doing with regards to the main game loop and calling the subroutines, when i put this into my .bas file as the first thing in the game loop its just being ignored.

 

Time for me to accept i am just not clever enough for this and give up i think.

If you feel like posting your code we can see what's happening,or send private if not comfortable posting on the forum.

Thank you. I am not near my pc right now, but I have been using the ‘shootbang’ example project as my starting point, so it would essentially be inserting the title screen into that .bas file. 
 

I figured it needs to go above where it calls the routine to move enemies?

You'll need to change a few things around in shootbang in order to display title screen ect,have you tried to create a project on your own yet?title screen,game screen and a sprite or two?If you want I started this in basic incase there is a JagJam 2023,you're welcome to go through my code.

Oh wow, this is great! Very cool!
 

Yes I did try that initially, just using the beginners guide in Jagstudio. I managed to change the background and add a couple of sprites.

 

I am open to any suggestions, and really appreciate them, so anything you can share with me would be great. Thank you so much.

I haven’t looked at it in the last week or so as I kinda lost hope , realised it was probably beyond my brain capacity 🤣

 

But yes please ! Any help you can give would be greatly appreciated.

Im gonna check this out.

Been looking at this, trying to get my head round the main game loop and all the sub routines. Its making a little more sense now.

[Jag_Mag]

It's great things are making sense to you,good job mdkdue!

You can always make it pretty for Jaguar later like this remake.

@Jag_Mag, the screens files are great, thank you for sharing. I've been tinkering with it and have a few questions if you have the bandwidth. I have tried replacing the background image with a new one:

Instead of seeing the screen as I am expecting, I see the following:

In addition to the screen being off center there is issues with the color I am noticing. 

 

This is my entry in rapinit.s:

; TITLE
	dc.l	1								; (REPEAT COUNTER) 				; Create this many objects of this type (or 1 for a single object)
	dc.l	is_active						; sprite_active					; sprite active flag

	dc.l	2								; sprite_damage					; Hitpoints deducted from target
	dc.l	352        						; sprite_gwidth					; GFX width (of data)	

 

Any thoughts on either issue? Perhaps someone else has some insight? Thanks in advance.

 

I'm sure these are basic questions so if there is a reference that would help I would appreciate being pointed to it.

 

This is the background file in question:

start-screen.bmp

I believe after continuing to work with this that the issue is the formatting of the bitmap image. Are there any tutorials or references for creating a bitmap image that is suitable for use?
