Sorry your browser is not supported!

I am a beginner in darkbasic pro, and this is my first game, except easy text guessing games, and other text games. this is an easy 2D game I try to make, but I have problems with to get the sprite to jump, my method have a lot of bugs, and it would be nice if you could help me I have also problem with sprite collision, I have tried, but can not still not make so the sprite stop when it hits something, could anyone help me with that? I am a completely a new beginner in darkbasic pro therefore are the game I trying to make not perfect, but I try as best I can. Other things I need help with are; when the sprite hits the goalflag a new map is coming, highscore, healthbar, spikes that hurts...etc

sorry for bad English

thanks for help

Here is a picture from my project

there are many ways to do jump here one of them:

thanks for the code, I will try it out tomorrow
Do you know how to get the sprite to not fall through the floor, adding collision? And is it possible to make collision with images??

Use sprite collision with another but remember to create a sliding effect.

The jumping code you gave me works perfect but what do you mean with to create a sliding effect, and how could I set up a sprite collision. Do I have to change my platform image to a sprite to use the sprite collision command, or could I make a collision with my player sprite with the platform image????

Here is a new picture from my project, but I have problems with to draw my score up on the left of the game window, could anyone help me with that? when I hit the coin-sprite the player will earn 1 point.

you have 3 options:

1- if you're using normal printing commands then you will have to print it in every loop.

2- turn your score results into sprite into sprites and create numbers image, then change the sprite image for a score.

3- use the command "set camera view 0,x1,y1,x2,y2" to define where the game must be drawn on the screen then the space left is part of bitmap 0 where you can normally use printing commands.

in my opinion, as you're still beginner, don't use the third option and I advise you to use the second option because it leaves your 2D game design limitless. while the third option is much better when your score board is very big that can take large amount of the screen leaving you with smaller game environment space.

Thanks you for your help but I have still problems. because when I print the score on the screen the score-number fall immediately directly into the floor. I have added a video, there you can see my problem. Here is my code

of course because you're not clearing the screen. use the command 'cls' to clear the screen before using print.

or use the command "text x,y,str$(score)" or "set cursor x,y : print score" then you don't have to clear the screen.

And remember to put code in code tags.

Basjak thank you for your help. Since I'm a beginner I have not learned all the commands and syntax in darkbasic pro. Therefore I have thought about buying a book. That could help me to get started with darkbasic pro. Do you have any tips about a good beginner book for darkbasic pro? I have read comments about the book (Hands On DarkBASIC Pro - Volume 1) is this a book you recommend for a beginner???

Mobiius I'll remember that for the next time I post my code

I started learning by reading hands on DBpro1 and then 2. yet DBpro have evolved since these two books printed but they make a solid reference for beginners. they very easy to follow and put you on a solid ground as beginner.

as well I think you're doing well as a beginner.

Thanks for help, here is a new video from my project. Now with a working score counter but I have still problems to get my player sprite to collide with the green squares (floor). Is it possible to make that my player sprite could collide with the green squares-floor??? the floor is not a sprite, and I have used paste image to paste them into the game. How could I make a collision???
