Drawing small texture

[bandrewk]

Hello,

 

I am experiencing a problem when drawing a small image in-game:

 

 

It is showing correctly in the editor, however, when I draw it in-game it looks awful. Drawing code (Context blend mode is set to alpha):

 

Context::GetCurrent()->DrawImage(textureGrab, Window::GetCurrent()->GetWidth() / 2, Window::GetCurrent()->GetHeight() / 2);

 

What am I doing wrong?

is it drawn with a different ratio?

[bandrewk]

I am not modifying it in any way. It is being loaded and directly drawn with the code above.

It looks like either blend isn't set properly or that the image draws over itself so much that the blend negates and everything is just full white. Try putting Context::GetCurrent()->Clear(); before drawing the image to see what happens.

I can't see your image here at work, but gamecreator says it's full white. I have this same issue, however it changes while I'm moving (mine is crosshairs for the player). In a project I have I am able to move around and in certain situations my crosshair model turns pure white, while in other situations it's normal. The map for this project is corrupt and I hope Josh is looking at fixing that so this bug can be reviewed.

Okay guys, thank you. I found a solution.

 

Adding

Context::GetCurrent()->SetColor(1, 1, 1, 1);

before drawing the image did the trick:

 

 

Seems a bit hacky but it's working.

Nice. I do that in my code too but only because I set transparencies so I guess that automatically took care of that potential problem. Do you have to do it every frame or just once before you enter the loop? I'm also curious about what GetColor returns without it but not a big deal. SetColor probably does something undocumented in the function that properly sets blend.

I made a mistake. GetColor() returned 255, 255, 255, 255. I had a line of code somewhere that said

context->SetColor(255, 255, 255, 255);

After changing it to 1,1,1,1 it worked just fine. Thank you gamecreator!

Ha, that definitely makes more sense. Glad you found that.
