Solar2D General Questions/Discussion

Hi Erich,

By joystick issue, I meant the integration of the joystick code with the game code, which I took care of.

Please let me know if you do want to look into the integration.

Enjoy your trip…

Nice work Ahmed, please keep us posted as you progress

#63

Thanks for the encouragement. 

In the first level I am interested to implement rain, not sure how, but looking into resources

#64

great work so far!

#65

Thanks brady for your kind words :slight_smile:

@ahmed_shahjada  for rain effects try Radiance @anaqim’s particle generator in the Corona marketplace.  He even has a rain demo somewhere with both rain falling from the sky and drops hitting the ground.

Rain is pretty easy, to be honest. Just create a displayGroup with about a hundred instances of the same image - a sort of white blurred streak on a transparent background. Give each of these images their own speed variable on creation, with some randomisation, just by adding a table entry for that sprite (for example: displayGroup.numChildren(i).speed = basespeed + math.random(10) )

Then move every image by their “speed” variable amount each frame, and when out of bounds (i.e. when their .y position is too high) reset their position by subtracting a value (like 1000 pixels).

Then you can rotate the displayGroup if you want to, for the angle of the rain.

Oh well. I was bored. Here you go: :slight_smile:

-------------- -- main.lua -- -------------- local rainGroup = display.newGroup() rainGroup.x = 320 rainGroup.y = 480 rainGroup.rotation = 30 local numberOfRainDrops = 100 local widthOfRainGroup = 400 local heightOfRainGroup = 400 local baseSpeed = 10 local maxSpeedVariation = 15 for i = 1, numberOfRainDrops do local rainDropImage = display.newRect(0,0,2,20) rainDropImage.x = -widthOfRainGroup/2+math.random(widthOfRainGroup) rainDropImage.y = -heightOfRainGroup/2+math.random(heightOfRainGroup) rainDropImage.speed = baseSpeed + math.random(maxSpeedVariation) rainDropImage.alpha = 0.5 + math.random(50)/100 rainGroup:insert(rainDropImage) end -- for loop local moveRainDrops = function(event) for i = 1, rainGroup.numChildren do rainGroup[i].y = rainGroup[i].y + rainGroup[i].speed if rainGroup[i].y \> heightOfRainGroup/2 then rainGroup[i].y = rainGroup[i].y - heightOfRainGroup end end end -- moveRainDrops Runtime:addEventListener("enterFrame", moveRainDrops)

@thomas6  Ha, I love it!  It might match this project well too.  Check out an @anaqim’s tutorial on Radiance rain as well, it’s well worth a look - supercool!

Wow the rain effect looks supercool! Thanks guys.

I am finding this forum a source of abundance of knowledge

I wish we could have an active chat room with an admin

@ahmed_shahjada There’s a Slack channel.

One or your fellow RPG developers also uses IRC, too.
