Open up the DIV IDE. If you choose to continue at the splash screen, we should see where we were when we left off yesterday.
First thing we need to do is create our jumping sprite.
close all the open maps via the MAP menu, and make a copy of graph 1 like we did previously.
edit the new graph using the graph editor to show our character in a jump motion.
Once you're done, drag this image into your FPG and give it the ID of 5.
Now onto the jumping code!
Add these three new private variable in your player PROCESS PRIVATE
list just below animcount as follows:
Code:
jumping = FALSE;
jump_offset = 0;
jump_power = 8;
The "jumping" variable we will use to know if we are jumping (or not)
The "jump_offset" variable is going to be used to keep track of how many pixels to jump every "FRAME"
The "jump_power" variable is used to store how strongly our player can jump.
Let's see how these are used:
We will use the spacebar to jump, lets add the condition to check for space being pressed in our code:
Code:
IF ( KEY(_space) && jumping == FALSE )
jump_offset = -jump_power;
jumping = TRUE;
END
This code does two things. First it checks if the spacebar is pressed, and then checks to see if we are already jumping. If we are, we don't want to
jump again! We'll later change this to also check if we are standing on the ground.
now below this, add another IF statement, to do some calculations on the Y variable.
Code:
IF ( jumping == TRUE )
y = y + jump_offset;
jump_offset = jump_offset +1;
graph = 5;
IF ( jump_offset > jump_power )
jumping = FALSE;
graph = 1;
END
END
This simplified jump routine changes the Y variable by a different ammount each frame and sets the graph to be 5 (which is our jump sprite), until the
offset has return to its original value. At which point it set jumping back to FALSE, and returns the graph to the walking sprite.
Run the code with F10, we should get something that resembles some reasonable jumping animation
Keywords learned in this lesson:
Code:
TRUE
FALSE
IF()
KEY()
_space
END
graph
y
That's all for this step. next time - running! humildadever - 14-3-2016 at 07:01 PM
I like Very goodRKSoft - 15-3-2016 at 02:47 PM

Thanks a lot. I waiting news upgrates..pommyman - 19-1-2017 at 10:29 AM
That's Brilliant!
I've got a little jumping man!RKSoft - 21-1-2017 at 04:21 PM
What about tutorial videos? Are they welcome?MikeDX - 22-1-2017 at 05:09 PM
Absolutely! I have done some on YouTube alreadyRKSoft - 23-1-2017 at 01:25 PM
Mike, i took your tutorial prg, played with your code and this is the current result :D
But, i found some baaaaaad bugs. I report them in the bug report forum.
This is the current version. A work of 2 days (2-3 hours per day).
ESC to kill
Q or ALT+X to quit the program
Cursor keys to move, jump and duck.
Kinda puts my tutorial to shame, you've take it to the next level and beyond!
on linux I had to rename screens.fpg to screens.FPG but apart from that it ran flawlesslyRKSoft - 24-1-2017 at 02:43 PM
Thanks, but you are a better programmer, you work on DIV .
So, if i finish this little 1-level programm i will prepare it to a tilebase system with an editor (sperate) for DIV users who search such a system.MikeDX - 24-1-2017 at 06:31 PM
I really like your colour scheme you have setup in the IDE. is that based on the blitz ide? RKSoft - 25-1-2017 at 02:59 PM
I think it could be like Blitz but in my Blitz ide i setup white background and black font color ^^. This (in my DIV) color scheme i like because it
is good to read the syntax, numbers etcl. When you are interest i can write the definitions here.
Mario of Many Colours.

Here's my effort.
It's Mario pretending to be Marvin Spectrum.
Keys: _up = jump
_right = roll
_down=slide
_z = red suit
_x = green suit
_c= blue suit
combinations of _z,_x,_c make the other colours.

That's very cool Dom. I'm a huge fan of the spectrum. DIV can even output a spectrum type mode via a dll.
Roland, yes I'd like your colour config please! dom cook - 1-2-2017 at 06:26 AM

Not that Spetrum, Marvin Spetrum is/was a nice mini game involving hopping through coloured light gates. (It was on Newgrounds I think)MikeDX - 1-2-2017 at 07:49 AM
Your colour scheme threw me off!
Still cool thoughRKSoft - 1-2-2017 at 05:19 PM
@dom cook
nice little programm, continue work and make it final dom cook - 1-2-2017 at 07:26 PM
@dom cook
nice little programm, continue work and make it final
Sure, just keep supplying the graphics. (Did you notice?)
Here's an update in which I've added music, removed a redundant key _right function, and changed the reverse scroll after collisions so that only the
player is affected (wrt screen coordinates).

It will be better when you pack all needed files into one zip
Nice run, but i'm confused with the keys. ^^

Hi, can you give me permission to translate this tutorial and post it on my blog?MikeDX - 2-2-2017 at 02:29 PM
