Hi! I’m new in the forum, and I need help with my project.

I created a map for my game with Tiled, but when drawing, I get this…

My code:

Which is the problem? Any idea?

Are the trees and the gras on the same layer?

3

No, the grass stay in “ground” layer and trees stay in “collision” layer.

4

Is the background of your trees transparent or black? I mean in the image file.

and Check your spriteBatch.Begin(…) the Blendstate might be the problem here.

5

In Photoshop I see transparent background.

I copy the code from this example:
https://github. com/craftworkgames/MonoGame.Extended/blob/develop/Source/Demos/Demo.Platformer/GameMain.cs
(I can’t insert more of 2 links D: )

This example not use the spriteBatch.Begin(…) to draw the map

The rendering doesn’t use SpriteBatch. You need to change the blend state between drawing layers.

Ahh… but, how can I change the blend state of the layer? Sorry for my ignorance, I’m so novice in this version of library :pensive:

See https://en.wikipedia.org/wiki/Alpha_compositing

...

// Render state to ignore transparency; transparent or translucent parts of images don't get alpha compositing.
GraphicsDevice.BlendState = BlendState.Opaque;

//TODO: Draw stuff that doesn't need transparency like ground layers or tiles that don't have any transparent parts.

// Render state to enable transparency; transparent or translucent parts of images do get alpha compositing.
GraphicsDevice.BlendState = BlendState.AlphaBlend;

//TODO: Draw stuff that has transparency like mask or fringe layers.

I can fix the problem, I hadn’t this line in my code:
“GraphicsDevice.BlendState = BlendState.AlphaBlend;”

Thanks for your help! :blush:
